Power tools and injuries

Going on from the previous thread, its amazing that more people do not maim themselves with power tools. It used to be normal to walk down a street with people hedge cutting and doing the lawn with mains powered devices. Usually there was at least one joint in the cable held together by tape. People got away with it, in the main. More recently of course not only do we have cordless devices, but the popularity of the Angle grinder as a general purpose tool has exploded, as have injuries from them. Obviously, I am now blind so cannot use them, but when you consider that the instructions are normally full of warnings about their dangers, you see people using them to cut things that can easily snag and kick back. It used only to be chain saws that injured people, but I think Angle grinders are now number one. Goggles? what goggles? Brian
