I wanted to call this Instructable "Make a heavy duty survival knife from an rusty file for less then 15 dollar in less then 2 hours with only basic tools", but sometimes less is simply more...
Survival. Again. I'm doing this - this what? this sport? this spirit? this way of life? I like the last one! - for many years and every survivalist comes to The Moment of asking the only question that counts: 'which knife???'
On the net you'll find thousands of 'survival knives' and a few brands offer really good stuff.
Instead of buying one, as a survivalist I prefered making one.
Making your own survival knife is going back to basics of survival: be inventive or die, or so.
Untill now I always used a customized tactical knife (my custom Muela Tornado 'Black Betty' - see picture). No need to spend an Instructable on this: take the knife, take a grinder, take a sander and you're done!
A few months ago I decided to make a survival knife from a file with only some basic tools. That evening project resulted in Y.U.R.T, I agree, the most ugly knife you've ever seen. But one that does the job!
YURT exceeded my best expectations. It's 200% yak-proof and a lot more reliable than a lot of the so-called 'survival' stuff you'll find on the net - with all my respect for those brands that matter.
Why a file? Because it's very hard steel, easy to find, and cheap.
All you need:
- a big grandpa's file
- a big hammer handle
- chemical anchor
- angle grinder
- safety gear
- weight: 272 gram - almost 10 oz
- overall length: 26.5 cm - a bit more than 10 inches
- blade length: 11.5 cm - 4.5 inches
- blade width: 3.5 cm - 1.4 inch
- maximal blade thickness: 0.7 cm - 0.27 inch
Step 1: Preparing the blade
- the tang aka 'root' has the same length as the blade!
- cut some grooves in the root so that the anchor will have more grip
For me, a survival knife needs four major functions:
- pointed for digging and carving
- an axe-styled upperpart for splitting
- a hollow shaped underpart for bushcraft and potato peeling
Use sander to finalize.
