Always check those rasp and files
Recently a friend came back from a trip with a bunch of old files for me. So as a thank you I was going to take the most interesting one and forge a blade from it. It was a thick wood rasp made by Nicholson. I cut the tang off (for use as the pommel) and forged out the blade. When I had the blade roughed in I heated to nonmagnetic and quenched in Parks 50. Since I wasn't positive about the steel I checked with a file, the file cut. So I went back, normalized and did the heat treat again changing quenchants. The file still cut. So I did what I should have done in the first place. Heated the tang of the file and quenched. It bent. I'd saved myself a lot of trouble by doing this, or I'd embarrassed myself as a knifemaker by giving it to some one as a cutting tool.
I'm sharing this as a reminder to always check those rasp and files before wasting your time on junk even if you think it's "good" steel. |

At least you learned something from it and I doubt that you're the Lone Ranger when it comes to trying to use a case hardened file to make a knife from.

Yepper!
Always test first. There are a lot of very attractive looking knives out there made from mystery steels that are no better than what you discovered. Nicholson used to be the "no issue gonna be great steel" go to, but as one can see ..... not so. Same with many other brands of files, saw blades, and other tools. I test extensively before forging into a blade for use. Just makes sense. A lot of folks are now going to ask "How do you test?" Subject has been covered so many times here and elsewhere, so use "SEARCH". Don't settle for testing procedures that support your thoughts, but use tests that tell the truth. Be honest with yourself, just like JMC has done. Thanks for sharing JMC....maybe some are listening. __________________ Carl Rechsteiner, Bladesmith Georgia Custom Knifemakers Guild, Charter Member Knifemakers Guild, voting member Registered Master Artist - GA Council for the Arts C Rex Custom Knives Blade Show Table 6-H |

Wood rasp, are often case hardened. I suspect this was the case in your file.
