Saftey glasses are for a false of security. My grandfather introduced me to exotic woods and was making, ironically, a good luck piece that was to have I believe maple and bubinga layered as a yin yang sunrise, when his table saw threw the whole thing at his face. Of course he had been carelessly standing on the wrong side of the saw, but his glasses shattered and the frame bent back around his head. He ended up losing that eye.
What's worse, is that he sold off his tools before I could learn how he could cut working merry-go-rounds out of just a slab of wood. Of course, if he had his tools still, I probably wouldn't have come to Warmoth for making a scratch bass.
