Making a knife from a file

[jtwodogs]

On stock removal of a file would the metal be tempered sufficiently to make a usable life, or would it need to be HT'ed.

 

[A.McPherson]

You'd probably need to temper it down to a useable hardness... Otherwise it might be too hard and chip with use.

If you look up in the stickies, there's a thread about making file knives.
