When I was starting out, I bought all my tools from my local Tandy. When I started pounding on a big strap end punch, the edge crumbled. As a longtime woodworker, I can sharpen anything, but the steel in that tool was junk. I went back to Tandy and asked the manager if there was anything of better quality. He was pretty blunt. "I won't buy that crap. Get your tools from Osborne."
I took his advice and have never looked back -- strap-end punched, round punches, bag punches, rotary punches, you name it. They hold up well and resharpen easily. I also have a few of the Weaver Master Tools, and they'er very nice indeed.
I do still use the little edge rounders from Tandy (all my big ones are from Osborne).
