Well, I went out to look for mine so I could tell you what it was... and can't find the dat burned thing. Not surprising, considering the current state of my shop and tools and everything else. It is my #1 tool, and I do just about everything with it... or I did, anyway.... It's around somewhere, but maybe I need to order another one, myself! I'll see if I can figure out which one it was... I'm thinking it was a #12 sweep, 6mm wide (close to a quarter inch wide).... maybe a 4....
