Actually, it wasn't chamise, at least not yet. Today, I spent about 4-5 hours on a weeding crew, cutting broom. The work was a mix of sawing and chopping, and the baby ganga got a workout. At the end, it was still sharp, even on the tip, which I had to stick into the ground a number of times in order to use the saw (all weeding took place on a slidey, 30 degree hill. The blade got laid where I could). While I was working, I gave it a touchup with the chakma once. When I got home, the edge needed cleaning and touchup, but it was still pretty sharp.
So yes, I'd say Steve's edge is definitely very functional. Until I go up against fire-hardened chamise, I can't give it The Test, but right now, it's doing well.
