I think one can easily figure out where one might stand on this issue... For me, the very first time I had a solid oak tsuba break in two and fly across the dojo, my stand on the issue was a done deal. No tsuba, those were my knuckles that would have been clobbered.
Yup, done that.
And while we could argue all day about whether that incident reflected my partner's lack of control, my lack of skill, or both, I'm just happy to still have a full set of intact, functioning fingers.
