The Ultimate Guide to Pocket Knife Types (2026)

You're staring at a wall of pocket knives. Or scrolling an endless grid of online listings. Every description reads the same: "premium steel," "smooth action," "everyday carry."

None of it tells you which knife actually fits your life.

So you guess. And a week later you're holding a regret. It's too bulky for your office slacks. Or it turns out to be illegal to carry where you live. Or the edge folds after a few days of breaking down boxes, and the thing ends up forgotten in a junk drawer next to dead batteries and twist ties.

That frustration isn't your fault. Most guides just throw product names at you and skip the part that matters: the handful of fundamental types that decide whether a knife becomes a daily companion or a $40 mistake.

This guide cuts through that. I've carried, used, and occasionally abused a lot of blades over the years, from office mailrooms to backcountry camps, and I've made the expensive mistakes so you don't have to. Below, you'll learn the five core pocket knife types, how their locks and blades actually work, and which one matches your tasks, your budget, and your local laws.

By the end, you'll be able to walk into any shop, or open any browser tab, and spot the right tool in about ten seconds, plus the ones to put back down.

You'll get a clear decision framework, a 2026 legal cheat sheet, and honest picks that have been carried in the real world rather than hyped by a retailer trying to move inventory.

Let's get you something you'll be glad to carry.

Pocket Knife Anatomy 101

Before we talk types, let's get the vocabulary straight. You'll see these terms throughout the guide, and knowing them now makes everything downstream click.

•             Blade: The cutting part. It comes in different shapes (drop point, tanto, and others we'll cover) and different steels (also covered below). The shape decides how it cuts; the steel decides how long it stays sharp.

•             Handle (or scales): The part you grip. The "scales" are the two slabs that sandwich the frame. Materials run from budget-friendly FRN (fiberglass-reinforced nylon, a tough textured plastic) up to G10 (layered fiberglass), Micarta (layered linen or canvas), titanium, and carbon fiber.

•             Pivot: The screw or pin the blade rotates around when you open and close it. A smooth pivot is the difference between a knife that flicks open with one hand and one that fights you.

•             Locking mechanism (lockup): The system that holds the blade open under use so it can't fold on your fingers. We'll break down the main ones below.

•             Pocket clip: The metal clip that holds the knife to the edge of your pocket. Many are reversible so you can carry tip-up or tip-down, or swap sides if you're left-handed. A deep-carry clip rides the knife lower and hides it almost completely.

•             Deployment method: How you open the blade. Thumb stud, thumb hole, flipper tab, nail nick, or a button on an automatic. Smooth, reliable deployment is most of what makes a knife feel "good."

Expert tip: When you're inspecting a knife in person, check two things. Wiggle the open blade side to side (that's blade play) and try to rock it up and down against the lock (that's lock rock). A well-made knife has essentially zero of either. If it wobbles on the showroom floor, it won't get better in your pocket.

The Main Pocket Knife Types (At-a-Glance)

The whole category boils down to five primary types. Each has a characteristic lockup, blade count, and job it's best at. Use the table to narrow things fast, then drop into the deep dives for the full story.

Type	Blade Count	Locking Mechanism	Best Use	Typical Price (2026)	Legal Notes
Single-Blade Folder	1	Liner, frame, crossbar/AXIS, or compression lock	Everyday carry; light-to-medium tasks; office and outdoors	~$30–$300+	Legal in most states. Blade-length limits often apply (commonly under 3–4"). The lock itself is rarely the issue.
Multi-Tool Knife	1–2 blades + tools	Liner lock, slipjoint, or lockback	Repairs, camping, DIY; the blade is secondary to pliers and drivers	~$35–$150	Blade usually under 3". A locking blade can be restricted in a few jurisdictions; the tool overall is rarely a problem.
Traditional Slipjoint	1–3	Slipjoint (non-locking)	Light cutting, food, collecting, gentleman's carry	~$15–$150	The most travel-friendly type, because it doesn't lock. Often exempt from length and lock restrictions.
Automatic / "Tactical"	1	Automatic (OTF or side-opening); assisted-opening is a separate category	Fast one-hand deployment; first responders; duty use	~$60–$500+	Heavily regulated and changing fast. Legal in most states now, banned or permit-only in some. Verify locally.
Friction Folder (Budget/Classic)	1	Friction (no mechanical lock)	Food prep, light outdoor work, travel, budget pick	~$10–$30	Non-locking, so legal in most places. Blade-length rules can still apply.

A quick honesty note on prices: knife pricing swings with dealer, variant, and steel. Treat the ranges above as ballpark. The named models later in this guide are priced individually, and even those move around.

Deep Dive: Single-Blade Folders

The single-blade folder is the backbone of everyday carry. One blade, one handle, one lock that keeps your fingers where they belong. If you want a do-it-all pocket knife and you're not sure where to start, this is almost certainly where you land.

Why One Blade Is Usually Enough

Most of what you cut in a day needs exactly one sharp edge. Opening packages. Slicing zip ties. Cutting an apple at your desk. A single-blade folder is lighter, slimmer, and faster than a multi-blade knife, because you're not fumbling to pick the right blade. You open, you cut, you close.

Expert tip: For city and office carry, a 2.5–3" blade is the sweet spot. It's long enough for the overwhelming majority of tasks but short enough to stay legal in most cities and not make a coworker flinch when you open your mail with it.

The Lockups That Define the Category

The lock is what separates a tool from a folding hazard. Here are the four you'll meet most often.

•             Liner lock: A thin metal leaf inside the handle springs sideways to sit behind the blade when it's open. Simple, proven, and on countless budget and mid-range knives. The downsides: it can wear over time, and closing it puts your thumb briefly in the blade's path.

•             Frame lock: A beefed-up liner lock where a cutout section of the handle itself becomes the lock bar. That makes it noticeably stronger laterally than a liner lock, which is why you see it on so many hard-use and titanium-handled folders. It's the lock I trust most for genuinely rough work.

•             Crossbar lock (Benchmade calls theirs the AXIS lock): A spring-loaded bar slides across the back of the blade's tang. It's fully ambidextrous, strong, and lets you close the knife without ever putting fingers near the edge. Once it's in your muscle memory, it's the fastest lock to work one-handed.

•             Compression lock: Spyderco's signature. A leaf wedges between the blade tang and a stop pin. It's very strong, it keeps your fingers clear on closing, and it lets the blade drop shut when you disengage it, which is why fidgeters love it.

For what it's worth on lock strength: a well-built frame lock can take a serious beating before it fails, and the crossbar and compression designs are widely regarded by testers as the most fingers-safe of the bunch because neither asks you to reach into the blade path to close up. If you want hard numbers, BladeHQ and various makers publish lock-strength data, but for normal carry, any of these four, executed well, is plenty.

Top Picks in This Category

The frustration: You bought a "good" folder once, and within a month the action got gritty, the edge gave up on cardboard, and the whole thing felt heavier in your pocket than it had any right to.

The fix: A folder that's light enough to forget you're carrying it and holds an edge through a real week of use.

The bridge : Benchmade Bugout (535): At 1.85 ounces with a CPM-S30V blade and the crossbar lock, the Bugout basically defined the modern ultralight EDC category and still sets the bar. It disappears in gym shorts. One nuance worth knowing: the standard Bugout's blade is about 3.24", which nudges over the 3" line some cities draw, so if you're in a strict jurisdiction, look at the Mini Bugout (533) at 2.82" instead. Around $180 (street prices often land lower), and Benchmade's lifetime sharpening and warranty soften the sting. The Grivory handle scales feel a touch hollow to some carriers; that's the common knock, and it's a fair one.

The premium-feeling alternative :  Spyderco Para 3: Compression lock, excellent ergonomics, and a sub-3" blade (about 2.95") that keeps it carry-legal in more places than the full Bugout. Newer base models run premium stainless (S45VN), and enthusiasts love it for cutting performance and fidget factor. Around $190 for the full version; the lighter FRN-handled Para 3 Lightweight is closer to $110 if you want to save weight and money.

On a tighter budget : Civivi Yonder (or the Elementum): Around $50 buys you a liner lock, D2 steel, and a fit-and-finish that genuinely embarrasses some knives twice the price. D2 holds an edge well but isn't fully stainless, so wipe it down and give the pivot a drop of oil now and then. If the Yonder's sold out, the Civivi Elementum is the same value story at the same price.

Deep Dive: Multi-Tool Knives

When a single blade isn't enough, the multi-tool steps in. These are the pliers-based or Swiss-Army-style tools that carry a knife blade alongside screwdrivers, scissors, can openers, and the rest. They're the ultimate problem-solvers, with one honest trade-off.

The Versatility Trade-Off

A multi-tool replaces a pocketful of gadgets. But the knife blade on one is usually shorter, thinner, and made of softer steel than a dedicated folder's. You're trading some cutting performance for a screwdriver and a pair of pliers. That's a fair trade if you reach for the drivers more than the edge. It's a bad trade if you mostly just need to cut things.

Expert tip: If your multi-tool has two blades, give them jobs. One stays the rough-duty blade for cardboard, tape, and scraping. The other you keep sharp for food and fine work. You'll stop wondering why your "sharp" knife smells like packing tape.

Plier-Based vs. Swiss-Army-Style

•             Plier-based (think Leatherman): Heavier and bulkier, but you get full-size pliers and, on better models, a one-hand-opening blade. This is the camping, DIY, and glovebox tool.

•             Swiss-Army-style (think Victorinox): Lighter and slimmer, built around small tools and a non-locking slipjoint blade. Better for the office, travel, and light tasks where pliers would be overkill.

Top Pick

The frustration: You're crouched at a campsite or under a sink, and the one tool you brought can't do the one thing you need.

The fix: A workhorse that folds a toolbox into your belt.

The bridge  Leatherman Wave+: Eighteen tools, including a one-hand-opening 420HC blade and locking implements, backed by a 25-year warranty and made in the USA. It's the standard every other plier-based multi-tool gets measured against. Around $100–$110. It's heavy (you'll want a belt sheath at roughly 8.5 oz), and that 420HC blade trades ultimate edge retention for easy sharpening, which is the right call on a tool you'll abuse.

Budget-friendly and pocketable Victorinox Super Tinker: Around $35 for a non-locking blade, scissors, and screwdrivers in the classic red housing. It rides in a pocket like a stick of gum and is about as travel-friendly as a tool gets.

Deep Dive: Traditional Slipjoints

Before modern locks existed, there was the slipjoint: a non-locking design that uses a backspring to hold the blade open under tension. These knives are steeped in history, and they remain some of the most legal-friendly, pocketable options you can buy.

The Non-Locking Advantage

Because a slipjoint doesn't lock, it's legal in more places than any other type. Plenty of jurisdictions that restrict locking blades or automatics still wave a slipjoint right through. They also read as gentlemanly rather than intimidating, which makes them ideal for the office or for use in public.

Expert tip: A slipjoint is not built for hard use. Don't pry with it, and don't twist the blade in a cut. The spring holds it open, but enough pressure in the wrong direction will fold it onto your fingers. Use it for slicing and light cutting, and it'll serve you for decades.

Classic Patterns and Their Heritage

Traditional slipjoints come in recognizable patterns, each with its own blade combination and history.

•             Trapper: Two blades, a clip point and a spey, originally meant for skinning game. Today it's a collector favorite and a tidy way to keep one blade for dirty work and one for clean.

•             Stockman: Three blades (clip, spey, and sheepsfoot) in a compact package. The classic "cattleman's knife," and still one of the most versatile traditionals going.

•             Barlow: A single long blade with an elongated bolster, a pattern that traces back to 17th-century England. Simple, sturdy, and unpretentious. It's woven into American folklore, too: Mark Twain hands young Tom Sawyer a "sure-enough Barlow" in The Adventures of Tom Sawyer, which tells you how ordinary and beloved these were.

Top Pick

The frustration: Every knife in your drawer screams "tactical" and feels wrong to pull out at a dinner table or a family barbecue.

The fix: Something handsome and unintimidating that still cuts clean.

The bridge : Case XX Trapper: Two chrome-vanadium blades, jigged bone scales, made in the USA. It's a timeless gentleman's-carry piece that doubles as a light-duty cutter and a collectible. Around $60–$80 depending on the handle material. No pocket clip and two-hand opening are the trade-offs; that's the nature of the breed.

Ultra-affordable entry : Rough Ryder Classic Carbon Barlow: Around $15 gets you a carbon-steel blade and genuine old-school charm. Carbon steel will patina and can rust if you ignore it, but that character is half the appeal

Deep Dive: Automatic and "Tactical" Knives

When fast one-hand deployment is the whole point, automatics enter the picture. These are the knives that show up in action movies, and they come with real legal strings attached, so read this section carefully before you buy.

Assisted-Opening vs. Automatic: Know the Difference

This distinction is not pedantic. It's the line between legal and felony in some places.

•             Assisted-opening: You start the blade moving with a thumb stud or flipper tab, and a spring kicks in to finish the motion. Because you initiate it, federal law and most states treat it as a normal folder, not a switchblade. Legal in far more places.

•             Automatic (switchblade): A button or switch releases the blade under spring tension with no manual movement from you. This bucket includes OTF (out-the-front) and side-opening autos. This is the heavily regulated category.

Here's the federal picture as it stands in 2026. The Federal Switchblade Act of 1958 is still on the books, but it only governs interstate commerce, mainly shipping autos across state lines and mailing them through the U.S. Postal Service. It does not, by itself, make it illegal to own or carry an automatic inside a state where state law allows it. Repeal efforts (the Knife Owners' Protection Act and the Freedom of Commerce Act) keep getting introduced but haven't passed. For the current, authoritative state-by-state breakdown, the American Knife & Tool Institute (AKTI) maintains the best free resource.

The trend is strongly toward legalization. Pennsylvania, Hawaii, Delaware, Vermont, and Virginia have all repealed or rolled back switchblade restrictions in the last few years, and a Massachusetts court struck that state's ban down as well. But "the trend is toward legal" is cold comfort if you're the one cuffed in a state that hasn't caught up.

OTF vs. Side-Opening Autos

•             OTF (out-the-front): The blade fires straight out the end of the handle. The cool factor is undeniable, but a small amount of blade play is more or less baked into the design (newer Microtech models fight this with their "zero blade play" system). Microtech is the benchmark here.

•             Side-opening auto: The blade swings out from the side like a normal folder, just driven by a button. It generally gives you a more solid lockup than an OTF.

Before you buy an automatic, check your local laws. In some states, carrying an auto without the right permit is a felony, and in a few, even ownership is restricted. This is the one category where "I didn't know" can genuinely ruin your week.

Top Pick

The bridge Microtech Ultratech: A premium dual-action OTF (the button both deploys and retracts the blade), running M390-grade stainless in an aircraft-aluminum chassis. It's precise, fast, and built like a watch. Around $300 and up. The honest cons: the price, the legal restrictions, and the trace of blade play inherent to OTFs.

More affordable and legal-friendly — Kershaw Leek: Around $60–$80 for an assisted opener (not an automatic) with flipper deployment and a slim, office-appropriate profile. The blade sits right around 3", which is the legal line in some cities, so measure twice. For most people who like the fast-deployment feel but don't want the legal headache, this is the smarter buy.

Blade Shapes and Their Purposes

The type of knife is only half the story. The shape of the blade decides how it actually cuts. Here are the five you'll meet most.

•             Drop point: The most versatile shape. The spine curves gently down to a strong tip, leaving a generous "belly" (the curved cutting section) for slicing. The forgiving all-rounder, and the right default for general carry.

•             Tanto: A reinforced tip where two straight edges meet at an angle. Excellent for piercing and scraping, less efficient for long slicing cuts. Common on duty and harder-use knives.

•             Clip point: The spine is "clipped" near the end to create a finer, sharper point. Great for detail work and piercing, though that thin tip is easier to break. The classic Bowie profile.

•             Sheepsfoot: A straight edge with a spine that curves down to meet it, leaving essentially no point. Ideal for cutting rope or seatbelts, or anywhere you don't want to accidentally stab what's behind the cut. A staple on rescue knives.

•             Wharncliffe: Like a sheepsfoot, but the spine tapers gradually all the way to a fine tip. Excellent for precise, controlled straight cuts and everyday utility work.

Expert tip: For a first knife, get a drop point. It does 90% of daily tasks without complaint and forgives a lot of technique mistakes while you're learning what you actually use a knife for.

Blade Steel Guide: From Budget to Premium

Steel is the heart of the knife. It decides how long the edge lasts, how easily you can bring it back, and whether the thing rusts in your pocket. You don't need a metallurgy degree, just four properties and four steels.

The Four Properties That Matter

•             Edge retention: How long the blade stays sharp under use. Often measured in standardized CATRA tests (how many cards it slices before dulling).

•             Corrosion resistance: How well it shrugs off rust. Higher usable chromium helps.

•             Toughness: Resistance to chipping or cracking under impact and lateral stress.

•             Ease of sharpening: How quickly you can restore the edge. As a rule, the harder a steel holds its edge, the more work it takes to re-sharpen. There's no free lunch; every steel balances these four.

Four Common Steels, Plainly Compared

•             420HC: Budget-friendly, very corrosion-resistant, and easy to sharpen. You'll find it on Buck and Leatherman blades. Edge retention is modest, so expect to touch it up often. That's a feature on a tool you'll abuse and resharpen in the field.

•             D2: A semi-stainless tool steel with strong edge retention and good toughness, popular in the $30–$80 range. The catch: it's only semi-stainless, so it'll spot with rust if you never wipe or oil it.

•             S30V: A premium stainless steel with a well-rounded mix of edge retention, corrosion resistance, and sharpenability. For years it's been the workhorse choice for Benchmade and Spyderco, and it's still a great place to land.

•             MagnaCut: The steel everyone's talking about, and for good reason. Developed by metallurgist Dr. Larrin Thomas and made by Crucible, it pulls a clever trick: it keeps its chromium "in solution" for rust protection and lets vanadium and niobium carbides handle wear resistance. The result is edge retention in the neighborhood of S35VN, toughness approaching non-stainless tool steels like CPM-3V and 4V, and corrosion resistance that beats even 20CV and M390. It's not the single best at any one property (S90V out-cuts it, 3V out-toughs it), but the balance is what's special.

Expert tip: Don't obsess over steel unless you're a heavy user. For most people, D2 or S30V is more than enough knife, and you'll spend more time enjoying a $50 D2 folder than agonizing over carbide structures. MagnaCut is excellent, and worth the premium if you want one blade that does everything with little maintenance. Just know you're paying for it.

How to Choose the Right Type for Your Lifestyle

You've got the types, shapes, and steels. Now let's put it together. Four quick questions get you to the right answer.

Step 1: Define Your Daily Tasks

•             Office / urban carry (opening mail, cutting tags, light food): a single-blade folder with a 2.5–3" drop point, or a traditional slipjoint.

•             Outdoor / camping (rope, food, light woodwork): a single-blade folder in a tougher steel (D2, S30V, or MagnaCut), or a multi-tool.

•             DIY / repairs (screws, pliers, occasional cutting): a multi-tool.

•             First responder / duty (fast deployment, seatbelt cutting): an automatic or assisted opener with a sheepsfoot or tanto blade.

Step 2: Check Your Local Laws

Here's the pain most guides skip. Knife law in the U.S. is a patchwork, it varies by state and city, and it changes. A knife that's perfectly legal one town over can earn you a citation at home.

When in doubt, carry a non-locking slipjoint with a blade under 3 inches. It's legal in virtually every U.S. jurisdiction, and it won't raise eyebrows. That's the safest universal default while you sort out your specific local rules. There's a full state-by-state cheat sheet at the end of this guide, with the strong caveat that you must verify it against current local statutes.

Step 3: Set Your Budget

•             Under $50: A solid D2 liner-lock folder (Civivi Yonder) or a classic friction folder (Opinel No. 8). Plenty of knife for most people.

•             $50–$150: The sweet spot. Premium EDC folders with S30V-or-better steel and refined ergonomics.

•             $150 and up: High-end materials (titanium, MagnaCut), American-made workhorses, or automatics.

Step 4: Consider Carry Style and Comfort

•             Weight: An ultralight Bugout (1.85 oz) vanishes in gym shorts. A Leatherman Wave+ (~8.5 oz) wants a belt sheath. Be honest about what you'll actually keep on you.

•             Pocket clip: Deep-carry clips keep the knife hidden; many knives let you set tip-up or tip-down. If discretion matters where you carry, this is not a small detail.

•             Handle material: G10 and Micarta grip well even when wet. Polished metal and smooth wood look great and get slippery with sweat or rain.

Top Product Recommendations by Type

These are the picks I'd actually spend my own money on, chosen from hands-on carry, community consensus, and value. Nothing here is sponsored. Prices are 2026 ballparks and move with dealer and variant.

Best Single-Blade Folder Overall  - Benchmade Bugout (535) · ~$180 Ultralight, crossbar lock, S30V, deep-carry clip. The default premium-light carry for a reason. Pros: featherweight, ambidextrous, excellent blade geometry, lifetime sharpening. Cons: the Grivory scales feel a little hollow to some; you're paying a premium for the name and warranty as much as the materials.

Best Value Single-Blade Folder - Civivi Yonder · ~$50 D2 steel, liner lock, G10 handle, and finish that punches well above the price. Pros: genuinely impressive value, smooth action, color options. Cons: D2 needs the occasional wipe and oil to stay rust-free; the clip isn't deep-carry.

Best Multi-Tool - Leatherman Wave+ · ~$100–$110 Eighteen tools, one-hand-opening blade, locking implements, 25-year warranty. Pros: versatile, durable, USA-made. Cons: heavy; the 420HC blade needs frequent sharpening (by design).

Best Traditional Slipjoint - Case XX Trapper · $60–$80 Classic American craftsmanship, two chrome-vanadium blades, jigged bone. Pros: timeless, non-locking (legal nearly everywhere), collectible. Cons: no pocket clip; two-hand opening.

Best Automatic - Microtech Ultratech · $300+ Premium dual-action OTF, M390-grade steel, aircraft-aluminum chassis. Pros: lightning deployment, superb machining, high fidget factor. Cons: expensive; legal restrictions; a little inherent blade play.

Best Budget Classic - Opinel No. 8 · $15 The iconic French friction folder: carbon-steel blade, beechwood handle. Pros: almost absurdly affordable, light, non-locking (legal nearly everywhere), a joy for food prep. Cons: carbon steel rusts if you don't dry it; no clip; the blade can stick a bit when new (and when the wood swells).

How we test: we carry each knife for at least two weeks of ordinary life, breaking down cardboard, prepping food, opening packages. We gauge edge retention by counting clean cuts through manila rope before the edge starts to drag, and we check lockup with static weight. We weight consistent quality control and a real warranty heavily, because a knife you can't trust isn't a bargain at any price.

Pocket Knife Maintenance and Safety

A maintained knife is a safe knife. Keep it up and a good blade lasts decades.

Sharpening Basics

•             Honing vs. sharpening: Honing realigns a rolled edge; sharpening removes a little metal to cut a fresh one. You'll do far more honing than sharpening.

•             A good starter system: The Work Sharp Guided Field Sharpener (~$35) is portable, beginner-friendly, and handles everything from soft 420HC to hard S30V.

•             Angle: Most pocket knives ship around a 20-degree-per-side edge. Keep that angle for a sensible balance of sharpness and durability.

Expert tip: A dull knife is more dangerous than a sharp one. Dull means you push harder, and harder means a slip turns into a cut. If you use a knife daily, give it a quick touch-up weekly and you'll never let it get scary.

Cleaning and Lubrication

•             Daily: Wipe the blade with a dry cloth after use, especially after food or tape.

•             Weekly: A single drop of mineral oil or a dedicated knife oil on the pivot keeps the action smooth and rust away.

•             Deep clean: If the action gets gritty, flush the pivot with isopropyl alcohol (disassemble only if you're comfortable and it won't void a warranty), let it dry, and re-oil.

Expert tip: Store knives somewhere dry. Avoid keeping a blade in a leather sheath long-term, because leather traps moisture and will quietly rust your edge.

Safe Handling

•             Always cut away from your body.

•             Never use a knife as a pry bar or screwdriver. That's what multi-tools are for, and it's how tips snap.

•             When closing a locking knife, keep your fingers clear of the blade's path.

•             If you drop a knife, let it fall. Catching a falling blade is how people end up in urgent care.

Frequently Asked Questions

What's the best pocket knife type for a beginner?

A single-blade folder with a 2.5–3" drop point and a simple, reliable lock. It's safe, easy, and versatile. The Civivi Yonder or a Spyderco Tenacious are excellent first knives that won't overwhelm you or your wallet.

Are automatic knives legal to carry?

It depends on your state and city. In 2026 the trend is strongly toward legalization, and most states now allow autos in some form, but several still restrict or ban them, and some require a permit. Federal law mainly governs shipping them across state lines, not in-state carry. Always confirm your specific local rules before buying or carrying one.

What's the difference between a slipjoint and a locking knife?

A slipjoint uses a backspring to hold the blade open under tension, but it doesn't lock, so enough pressure on the spine will close it. A locking knife (liner, frame, crossbar, compression) has a mechanism that physically blocks the blade from folding until you disengage it.

How often should I sharpen my pocket knife?

It depends on use. For light daily carry, hone weekly and do a full sharpening every one to two months. If you cut abrasive stuff like cardboard or rope, expect to sharpen more often. The simple test: if it won't slice through a sheet of paper cleanly, it's time.

Can I bring a pocket knife on a plane?

Not in your carry-on. TSA prohibits knives in the cabin (the lone exception being round-bladed plastic or metal butter knives). You can pack a knife in checked luggage if it's securely wrapped. Check the current TSA guidance before you fly, because the details get updated.

What's the best blade steel for EDC?

 For most people, S30V or D2 hits the best balance of edge retention, corrosion resistance, and price. MagnaCut is the top all-rounder if you want one low-maintenance blade that does everything, at a premium. 420HC is fine for light use but needs frequent sharpening.

How do I know if a knife is good quality?

Look for a brand that stamps the steel type right on the blade, smooth action with no blade play or lock rock, and quality handle materials (G10, Micarta, titanium). Read reviews from trustworthy sources. Be wary of any knife that won't tell you its steel, that's usually "mystery steel," and usually a sign of corners cut elsewhere.
