September 11, 20169 yr Here is my first farriers rasp knife. It's stock removal. It is also the first knife I heat treated. It has a solid mesquite handles, that I milled out myself. Need some minor touch ups.
September 11, 20169 yr Author Thanks. In don't mind critiques, I'm by no means an expert. Just a guy that loves knives
September 12, 20169 yr Author No I didnt. The files had beven in my grandfathers old shop. They are older than I am, (42). So I used them

So I used them This is one of the test I use to determine if a file is good steel or case hardened. Heat only the tang of the file up and quench in water. Clamp the file tang up in a vice and hit the tang with a hammer to break it. (wear your safety gear). If the tang breaks clean it has enough carbon to harden, if the tang bends over it doesn't. I made the mistake of forging a knife from a very old Nicholson wood rasp. I assumed since it was a Nicholson, it would be good steel. I forged the blade, ground and quenched it. After hardening always check and see if a file will cut the edge, on this one it did. I normalized and did the hardening procedure again with the same outcome. I went back and tested the tang, and wouldn't you know it, it bent over. Turns out Nicholson used case hardening on some of their rasp. Moral of the story, always check your mystery steel before spending time making something from it.
September 12, 20169 yr I agree with TJ on the bevel. If it is too obtuse you essentially have a wedge/chopper, slim it down some and it will slice without wedging into the item. Overall shape looks good.
September 13, 20169 yr Good, don't forget you probably need to test each one you use as a manufacturer can change what they use and their process at the drop of a penny! With time you find out that some brands/ages seem to tend towards better metal---which generally is just lulling you till you spend a lot of time on one only to find out that it was case hardened...
September 15, 20169 yr Don't be afraid to push that grind back a little farther. Looks good. Glad to see you test them. Keep it up!
September 19, 20169 yr That a pretty slick looking first rasp knife well done. I really like the shape of the handle on it.
