DIY Knife from a hex wrench

This is a pic I found from the web. I forgot to take a original before I decided to document this but that’s pretty much how it looked before I grind it up.

Sharpened one side with a filer

Sharpened with stone and buffed with polishing wheel and paste (not shown)

Pre-drilled holes for handle and lanyard hole
and outlined wood for handle

    Nice job on the knife !
    How hard is the steel? I keep picturing the generic wrenches that come with bikes to assemble.
    Where can you find them? Thanks, IAC.

    Thanks. I am not sure how hard the steel is but its good enough to hold the edge. This wrench came with my Ryobi Sliding Compound Miter Saw TSS100L. I did some looking up and this model is 089100113808. Ryobi has a parts store selling a replacement part for $2.40. Not sure how much shipping is though. Good luck!
