having just got 24 stitches out of my hand, i have a whole new attitude about safety equipment.
i'm slow and careful and pay attention and haven't been seriously hurt in over 4 decades of saw use. When it happens, it's fast.
So my new slippers are clodhoppers with steel toes and kevlar padding. The tongue is double thick and the pretty new shoelaces are yellow kevlar, the thickest I could get through the holes. It's mm's that count, if you can stop the damn thing after your hides been chewed but before the parts that let you move are hit, that's still winning.
