Can you really make a knife from an old file?

well, The little one is pretty small... the big one is a little too big, so it only made sense to make a 3rd one thats "just right"

overall lengths 6, 8, and 10 inches.
 
Looks good.... I'm not a fan of the point profile, but it would make a pretty good skinning profile....

Great start. In addition to tapering the blade from the spine towards the cutting edge, maybe consider tapering the thickness of the blade from the ricasso toward the tip.
 
Nice work!

There was an article about making a camp knife from a hacksaw blade in Field and Stream or Outdoor life a few months ago. I would have never thought of something like this. Looks like I might have a winter project now.
 
files are so passe, now this baby was made with real high tech material. a lawn mower blade! :D

YOU MUST USE "OLD" FILES..NEVER NEW ONES, ANYTHING BEFORE 1960 SHOULD BE FINE // NEVER EVER USE A BAYONETT, THEY ARE SOFT STEEL AND WILL NOT HARDEN.

YOU MUST SOFTEN THE BLADE BEFORE YOU DO THIS WORK OR YOU ARE GOING TO USE
YOUR GRINDERS , DISCS, TOOLS, UP AT A RATE OF ABOUT 5 TIMES FASTER THAN NESSASARY...FILES ARE HARD !


ONCE SOFTENED, (YOUR WORK LOOKS REALLY NICE), ( most people like to leave some of the file groves for looks)

next after its all shaped and 90 % finished, you need to harden it, getting it soft red and dropping it in a tub of old oil or tranny fluid works ok, ( make sure thats a metal tub) and watch out for flame up when you do that, now that its properly hardended, you must
temper it, put it in your oven for about 3 hours on 350 degrees.. that will relax the harden and give the blade flex, all done clean it up , handle and sharpen it, then oil it and your done
 
Zombiemaster couldn't have put it more succinctly with one exception. I have used many different types of files and it is hit or miss as far as carbon content. Not all files after 1960 are bad for knifemaking. My advice is to sample quench a piece of the file you are going to use. That should give you some idea of it's ability to harden. I forge my file knives so cutting off a small piece and hardening it is not difficult. It may be if you are just grinding and do not want to lose the hardness already in the file.
 
I've found Nicholson "Black Diamond" files to be excellent knife making fodder regardless of year of manufacture.

Also, make sure you clean every last molecule of oil off of that blade before sticking into your hot oven. Otherwise, you'll have a house full of acrid oil smoke that will linger for a looong time. And, your wife will not ever let you forget about it either. Some things even flowers and diamonds won't remedy. Trust me...
