Best for: Everyday carry and heavy use Why it made the list: The Paramilitary 2 features a CPM S30V blade that holds an edge far longer than budget steels, a compression lock that is stronger and safer than liner locks, and a contoured G-10 handle that fits most hand sizes comfortably. Owners report it stays razor sharp through weeks of cutting cardboard and rope.

Folding Knife Buying Guide

Blade Steel

Blade steel determines edge retention, corrosion resistance, and ease of sharpening. Common steels include 8Cr13MoV (budget, easy to sharpen), AUS-8 (good all-rounder), and CPM S30V (premium, long-lasting edge). Higher carbon content improves hardness but reduces stain resistance. For daily cutting, a steel like 8Cr13MoV is adequate; for heavy use, invest in S30V or similar.

Lock Mechanism

The lock holds the blade open during use. Liner locks are common but can fail if the liner is thin. Frame locks are stronger but may require adjustment. The compression lock (Spyderco) and AXIS lock (Benchmade) offer superior strength and ambidextrous operation. Avoid cheap lock backs that can pinch fingers.

Handle Ergonomics

Handle material affects grip and weight. G-10 is durable and textured for wet hands. Nylon is lightweight and inexpensive. Stainless steel is heavy but sturdy. Choose a handle shape that fills your palm without hot spots. Check for a deep carry pocket clip that doesn’t attract attention.

Safety Notes

  • Always cut away from your body and keep fingers clear of the blade path.
  • Use the lock every time; never rely on friction alone.
  • Store knives closed and out of reach of children.
  • Inspect the pivot and lock regularly for wear.

What to Avoid

  • Smith & Wesson SWMP4LS: Weak frame lock slips under moderate pressure; blade steel is soft and dulls quickly.
  • Tac-Force Speedster: Unreliable liner lock; blade play out of the box; cheap pot metal handle.
  • M-Tech Xtreme: Poor heat treat; blade chips easily; thumb studs break off.

FAQ

What is the best lock type for a folding knife?

Compression locks and AXIS locks offer the best strength and safety. Liner locks are adequate for light use but can fail if the liner is thin.

How often should I sharpen my folding knife?

Depends on use. For daily carry, touch up on a ceramic rod every week or two. Full sharpening every few months.

Can I carry a folding knife in my pocket?

Yes, most folding knives come with a pocket clip. Ensure the knife is legal in your area (check blade length restrictions).

Final Verdict

The Spyderco Paramilitary 2 is the best folding knife for most people because of its CPM S30V blade, compression lock, and ergonomic G-10 handle. If you want a more affordable option, the Ontario Rat 2 delivers great value with AUS-8 steel and a reliable liner lock. The Kershaw Cryo is a decent budget pick for occasional use.
