I've been researching and purchasing files and rasp over the last little bit. Good ones are hard to find,..at least they were for me. As with anything else you get what you pay for. Here is a couple of links if any of you guys are in the market for some future buys for your shop. I use mine for powder horns and wood,..so I'm after coarse sharp toothy files. I also picked up some rasps. I hate most all of the other junk out there https://www.ottofrei.com/jewelry-tools-equipment/bench-tools/files ,......larger files start on about page 4 https://www.corradishop.com/ Have several products from these guys,........love the Gold Precision rasps. They ship direct from Italy....arrives in 2 days.
