George, I have big hands, too. I still can’t convince Mark Harrell at Bad Axe (even though we’ve met in person) that I need his biggest handle and maybe even a bit bigger. There are two brands of motorcycle gloves I’ll buy, one in a 3XL, and the other in a 4XL. At least they offer ones that are big enough. For yard work, I order my leather gloves online, because none of the stores here in Santa Fe even stock the one-size-too-small size that I can use if I cut open the fingertips and let my fingers stick out the ends. So I find my saved purchase from previous years on Amazon and reorder the exact same gloves.
Anyway, I’ve found I can work with too small of a handle on a saw for a while. It’s just not especially comfortable. But if my push saws are flexing, I’m doing something wrong. The back should be keeping the saw plate straight and well-tensioned, and if it’s not, the saw goes off to Bob for tweaking if I can’t get it working myself. Sharp fixes darned near everything.
