Knife Buying Guide: How to Choose the Right Knife

Knife buying guide: Choosing the right knife comes down to how you plan to use it. With thousands of options available, the key is focusing on function first.

This knife buying guide breaks down what matters so you can quickly find a knife that fits your needs.

Step 1: Know Your Use Case

The single most important factor in choosing a knife is what you’re going to do with it. A knife optimized for everyday carry is a poor choice for field dressing deer, and a heavy outdoor fixed blade is awkward in a pocket. Start here before looking at anything else.

Everyday Carry (EDC)

You want something lightweight, slim, and quick to open one-handed. Blade length of 2.5–3.5 inches keeps you legal in most jurisdictions. Look for a reliable locking mechanism (liner lock, frame lock, or lockback) and a pocket clip. Popular EDC choices include the Spyderco Paramilitary series, Benchmade’s Griptilian, and anything in the CIVIVI or Kershaw lineups for great value.

Outdoor and Bushcraft

Fixed blades dominate here. You want a full-tang knife (the steel runs the full length of the handle) with a blade between 4–6 inches, a Scandi or convex grind, and a comfortable handle that won’t cause fatigue during extended use. Mora, ESEE, and Condor make excellent outdoor knives at every price point.

Hunting

Hunting knives typically have drop point or clip point blades designed for skinning, caping, and processing game. A gut hook is useful for field dressing without puncturing the stomach. You want something easy to clean, with a handle that stays secure when wet. Consider a dedicated fillet knife if you spend time fishing.

Kitchen

A good chef’s knife handles 90% of kitchen tasks. German-style knives (Wüsthof, Victorinox Fibrox) are heavier and more forgiving. Japanese-style knives are thinner, harder, and hold a sharper edge but require more care. A paring knife and a serrated bread knife round out a complete kitchen set.

Tactical and Self-Defense

These knives prioritize quick deployment and secure grip under stress. One-hand opening via a thumb stud or flipper is standard. The best tactical knives are also practical everyday tools, they don’t have to look aggressive to be capable.

Step 2: Folding or Fixed Blade?

Folding knives are more portable and legal to carry in more places. The blade folds into the handle, making them pocket-friendly. The tradeoff is that a folding mechanism is a potential failure point, and folding knives require one hand to open.

Fixed blade knives have no moving parts. They’re stronger, easier to clean, and deploy instantly. The downside is that they require a sheath and are less convenient to carry daily. For outdoor and survival use, a fixed blade is generally preferred.

For most people, a folding knife handles everyday tasks while a fixed blade stays in the pack or on the belt for outdoor adventures.

Step 3: Understand Blade Steel

Steel affects how sharp an edge gets, how long it holds, and how much maintenance it needs. Every steel involves tradeoffs between hardness, toughness, and corrosion resistance.

Budget steels (good value)

8Cr13MoV / AUS-8 – Common in budget knives. Easy to sharpen, decent corrosion resistance, won’t hold an edge as long as premium steels.
14C28N – Sandvik’s improved budget steel. Better than 8Cr13MoV and found in many Kershaw knives.

Mid-range steels (sweet spot for most users)

D2 – Semi-stainless, excellent edge retention, slightly prone to rust if neglected.
VG-10 – Japanese stainless. Hard, sharp, good corrosion resistance. Used extensively by Spyderco.
S30V – American premium steel. Great balance of edge retention and toughness.

Premium steels (serious users)

S35VN / S45VN – Refinements of S30V with improved toughness. Industry standard for high-end production knives.
M390 / 20CV / 204P – Nearly identical steels made by different manufacturers. Exceptional edge retention and corrosion resistance. Harder to sharpen.
CPM-3V – Optimized for toughness over hardness. Excellent for hard-use outdoor knives.

For most users, anything from D2 to S35VN hits the sweet spot. Ultra-premium steels offer real benefits but are difficult to sharpen without the right equipment.

Step 4: Blade Shape and Grind

The blade shape determines what tasks the knife excels at:

Drop point – Versatile all-around shape. The spine curves down to meet the tip. Most EDC and hunting knives.
Clip point – Fine tip for detail work. Common on Bowie-style knives.
Tanto – Reinforced tip for piercing. Tactical-focused, less versatile for general use.
Sheepsfoot – Rounded spine, straight edge. Safe for rescue and utility work.
Wharncliffe – Flat edge, curved spine tapering to the tip. Excellent for controlled cuts.

The blade grind determines how the blade is thinned to the edge:

Hollow grind – Thin, razor-sharp edge. Common on EDC knives. Easy to sharpen.
Flat grind – Tapers from the spine to the edge. Versatile and strong.
Scandi grind – Single bevel grind with no secondary bevel. Excellent for woodwork and outdoor use. Very easy to touch up in the field.
Convex grind – Curved grind that’s incredibly tough. Harder to sharpen but excellent for splitting and chopping.

Step 5: Handle Material and Ergonomics

The handle determines how comfortable and secure the knife is in your hand. Common materials:

G-10 – Fiberglass laminate. Lightweight, textured, impervious to moisture. Excellent all-around.
Micarta – Linen or canvas embedded in resin. Warm, natural feel that improves with use. Slightly heavier than G-10.
Carbon fiber – Lightweight and stiff. Looks premium. Less impact-resistant than G-10.
Aluminum – Durable and lightweight. Can be slippery when wet without texture.
Wood – Traditional, beautiful. Requires more maintenance, can crack if neglected.
Titanium – Light, strong, corrosion-proof. Expensive. Often used for frame lock handles.

Ergonomics matter as much as materials. If possible, handle the knife before you buy. A knife that’s uncomfortable to hold won’t get used.

Step 6: Locking Mechanisms (Folding Knives)

A reliable lock is a safety feature. Understand what you’re buying:

Liner lock – A spring steel liner snaps behind the blade. Simple, reliable, easy to close one-handed. Most common mechanism in production knives.
Frame lock – The handle itself acts as the lock. Stronger than a liner lock. Common in premium folding knives.
Lockback – A spine-mounted spring locks the blade open. Very secure, but requires two hands to close.
Axis lock (Benchmade) – An ambidextrous bar locks the blade. One of the smoothest and most secure mechanisms available.
Ball bearing detent – Used on many flipper knives. A ball bearing holds the blade closed until flipped open. Smooth and satisfying.

What to Spend

You don’t need to spend a lot to get a capable knife, but quality does scale with price:

Under $30 – Functional tools. Budget steel, basic construction. Kershaw, Rough Rider, and Tac Force offer good options here.
$30–$80 – Solid mid-range. Better steel, tighter tolerances, more ergonomic designs. CIVIVI, QSP, and Kershaw higher-end lines.
$80–$200 – Premium production knives. S30V and better steels, excellent fit and finish. Spyderco, Benchmade, Buck.
$200+ – High-end production and custom collaborations. Premium steels, superior materials, tight tolerances. Microtech, Medford, WE Knife.

For most people, the $50–$150 range offers the best value. You get premium steel and excellent construction without diminishing returns.

Legal Considerations

Knife laws vary significantly by state and municipality. Blade length limits, locking mechanisms, and carry method (open vs concealed) are all commonly regulated. Automatic knives are restricted or prohibited in several states. Always check the laws in your area before purchasing or carrying any knife. Atlas Knife Co includes shipping restrictions on automatic and other regulated knives at checkout.
