Higher-carbon steels like 1095 or CPM-S30V hold an edge longer but take more effort to resharpen and can rust if neglected. Stainless steels like 8Cr13MoV or 420HC sharpen up quickly and resist corrosion well, trading off some edge retention for that convenience. Fixed blades are stronger overall, easier to clean, and better suited to hard use like batoning or field dressing; folders trade some strength for pocketability and a shorter carry profile.
Edge grind affects how a blade performs on different tasks — a flat or hollow grind slices cleanly and is easy to resharpen, while a convex grind holds up better to chopping and heavy use. Serrated edges saw through rope and fibrous material faster but are harder to sharpen at home. Opening mechanism (thumb stud, flipper, assisted, or automatic) is largely personal preference for use, but assisted and automatic openers carry extra legal restrictions in some places — worth checking before you buy, especially for carry outside your home state.
Common questions
What's the difference between fixed-blade and folding knives?
A fixed blade is a single solid piece with no moving parts, making it stronger and easier to clean — better for hard use like camp chores or field dressing game. A folding knife pivots into the handle for compact, pocket-friendly carry, trading some strength and rigidity for convenience.
Are assisted-opening or automatic knives legal to carry?
Knife laws — including blade length limits and rules on assisted-opening or automatic knives — vary by state, county, and even city, and change over time. This isn't legal advice; check your state and local statutes before buying or carrying, especially if you'll be crossing state lines or carrying in a vehicle.
What steel holds an edge the longest?
Higher-carbon and powder-metallurgy steels like CPM-S30V, CPM-154, or M390 generally hold an edge the longest, but they're slower to resharpen and often cost more. Budget-friendly steels like 8Cr13MoV sharpen quickly and resist rust well but need touch-ups more often. Match the steel to how often you're willing to sharpen.
How do I keep a knife from rusting?
Wipe the blade dry after use, especially after contact with acidic foods, saltwater, or blood, and apply a light coat of oil before long-term storage. Stainless and coated blades resist corrosion better than plain carbon steel but aren't rust-proof — carbon steel in particular needs regular maintenance to stay clean.
