One time I was cleaning up on the workbench and there was a little pile of the wires that had been flung out of the wire wheel on my bench grinder. I swept my hand across them and felt a stab of pain as one of the wires went straight through the tip of my middle finger about a quarter inch from the tip. It looked funny but I remember an old square rigged sailor told me why knives have a blood gutter on them . He said that the body holds on to a flat blade and the blood gutter lets in some air to overcome the vacuum. Well I grabbed the little wire with my teeth and yanked it out.Dull pain for a couple of days. Now I have a brush lying next to all my machines.
