That looks really cool...awhile back there was a guy that had some knives made from old files that he made via stock removal. on all of his knives he made sure to leave visual remnants of the file teeth...it looked pretty cool...but I have been wondering what it would look like to do the same thing with old rasps since my farrier is an aspiring blacksmith as well and has a large quantity of old rasps saved up. I'm sure I can get him to share a few with me...
I really like how it turned out...
