File knife.......

Hey Tiiiiiim,
The quick rundown......It's just like forging any other knife....I heat the file up in my forge and use my hammer and anvil to form it into the shape that I want...then clean it up on the grinder....then do the heat treatment(this one I had to do twice to get what I wanted)...then hand sand and etch as needed to get the finish I'm looking for....this one has a 1500 grit finish on it.

Thanks for all the nice comments fellas!

Burt, I just might start using files for all my knives, but then what would I do with the 1000+lbs. of 1095fg that I have?!:D

SWEET I am making my first knife out of a large broken file that I broke while on the job welding some years ago. It just kept calling to me to make a knife of it. So begins my task,

If i wanted to make a knife out of an old file just using grinders and files (not forging it) is that possible? or are files them selves not sufficiently heat treated to hold an edge?
 
Tiiiim,
Sure you can. You will need to do one thing or another tho. Either you need to temper the file(because right now its too hard) then keep it cool while grinding to preserve the heat treat...this will take a while and use up abrasives, or... you need to anneal the file to soften it so it can be worked and shaped into the knife blade...then re- heat treated(quench and temper) to make it a usable knife blade.
In the forging that I did, it took away the original heat treatment of the file...then after rough grinding it I needed to re-heat treat(quench and temper) again. On this particular knife the first time I did it the "hamon" or temper line was to low to the edge..so I redid it to bring that line up a bit higher. I also had to take extra time in the tempering....I did my first temper and then tested the edge...it would chip out....re temper at 5% higher then tested again...I had to do this several times before the blades edge would flex and not chip out.
Good luck and let us know how it turns out for ya!:thumbup:
