A tinner in Council Bluffs told me to stop running my snips through the same slot, and it fixed my whole pace
Was hanging duct on a little strip mall job outside Council Bluffs back in April, second day on a run of 26 inch rectangular trunk. The old timer doing the fittings next to me watched me cut for maybe 10 minutes and finally just said, "You're wearing one groove into those jaws and then cutting with the dull side." I told him I'd been doing it this way since I started. He handed me his 12 inch offsets and said try the back third of the blade for a while. I did, and the difference in how square my cuts came out was not subtle. What got me was that the jaw starts to roll over after a few hundred cuts and you don't feel it, you just start fighting the metal and blame the gauge. Now I mark the blade with a paint pen and flip to a fresh section before a big run. Cost me nothing but a paragraph from a guy I'll probably never see again. Any of you run your snips to the back of the jaw on purpose, or do you just toss them and grab a new pair when they mushroom?
