Vince-
You should anneal a couple ( oven, weed burner, etc) and then cut/grind hay-string knives out of them.
I got too many things to do now as it is. I welded a triangle knife form a sickle bar onto my pitch fork between two tines and that cuts the hay strings pretty good.
I have bought a few good Nickelson rasp over the years, but was at an auction and they had dozen rasp that had a little rust on them, other than that they were new, still in a the wrapper. I bought them all for $6.
I'll never use them all up so I have one in my truck, in my horse trailer, in the tack room, next to the stalls.. Heck I use them more to make gun stocks than to rasp hoofs
