What Is a Fixed Blade Knife? A Plain Guide
A fixed blade knife is a knife whose blade does not fold. The steel of the blade carries on into the handle, so there is no hinge, spring or lock between your hand and the edge. Because it cannot fold, it is carried in a sheath rather than a pocket.
Fixed blade or folding knife?
| Fixed blade | Folding knife | |
|---|---|---|
| Strength through the handle | No moving parts | Depends on the pivot and lock |
| Cleaning | Rinse and dry | Dirt and fat collect in the hinge |
| Carry | Sheath on the belt | |
| Ready to use | Draw it | Open and lock it |
That is why fixed blades are the standard for hunting and outdoor work, and folders for everyday pocket carry. Carry laws for both vary by state and city, so check yours.
What is the tang?
The tang is the part of the blade steel that runs into the handle. On a full tang knife it runs the whole length and width of the handle, with the handle scales pinned either side, and you can see the steel along the spine and the butt. On a partial tang knife the steel stops partway inside the handle. Full tang puts more weight in the handle and suits large working knives. Partial tang is lighter and is the traditional build for a hunting knife around 10 inches.
What size fixed blade do I need?
- 3 to 5 inch blade: hunting, field dressing, camp cooking, everyday outdoor work.
- 6 to 9 inch blade: more reach for large game and camp work. Heavier on the belt.
- Under 4 inches: worth knowing if your state or city limits the blade length you may carry.
What is a fixed blade knife used for?
Field dressing and skinning game, food preparation at camp, cutting rope and cord, carving tent pegs and feather sticks, and general cutting outdoors. It is a cutting tool: prying, hammering on the spine or splitting wood are how fixed blades get damaged.
What should come with it?
A sheath made for that blade, so the knife cannot slide out when you bend over. Leather is traditional; let it dry before the knife goes back in, because leather holds moisture against steel. Every Bigcat knife is a fixed blade with its own leather sheath, from the 8 inch Karambit Desert Fox to the 14 inch Patriot.
Frequently asked questions
Is a fixed blade stronger than a folding knife?
Through the handle, yes, because there is no pivot or lock to give way.
Is a fixed blade knife good for camping?
Yes. It cleans easily and handles food, cord and carving. Carry a small axe or saw for firewood.
Full tang or partial tang?
Full tang for large working knives, partial tang for a lighter hunting knife around 10 inches. Neither is simply better.
