I purchased a nice farriers rasp (Save Edge) off eBay made in the good old USA and couldn't be happier. I have 5 draw knives and my favorite is still the first one that a friend gave to me years ago. It's a Jaxson, 10 inch, straight edge, and I've never seen another one like it, so don't be afraid to try some old unknown maker brand tools. Just make sure that they aren't too badly rusted and stay away from anything pitted or with heavy gouges in the working blade area.
Jawge, thanks for the link. I've been using your site and help for years and this is the first time (I think) I saw that one.>>>Fred
