Thanks guys. I spent a few hours today, sanding some of them a bit further on the belts, it's all hand sanding from here on. Killed two of them in the process - I over-sanded a small one, i.e. by the time I had it symmetrical, there wasn't much handle left... The other one didn't pass the breakage test. Cross-cut woods are not as strong as others, so I usually try to break them with reasonable force to make sure they will hold up and don't have hidden cracks. The black palm handle (5th from left in top row) didn't make it. I may give up on that stuff in cross-cut. It's brittle to begin with and this is not the first one that dies.
