Thank you so much for that information! It is expensive, but well worth the price, I think, for the safety issue. Plus, it looks so easy to use. I once cut off just a small bit of my pinky finger because it was slightly hanging over the edge of the ruler.
That finger end was squared off for a while. I was so lucky it wasn't worse. I think I'll get this before my luck runs out, lol! After all, I'm just getting older (and weaker, and clumsier, and my eyesight's not what it used to be, etc., etc.).
