I do multi-tasking on many things, but not with TS or BS or routers. I KNOW where my hands are, I KNOW where the pieces of wood is going. I can walk and chew gum at the same time but when it comes to sawing, I don't think of other things. I concentrate on the saw, wood placement, my hands and how everything is working together - or not. I am not frightened for saws, but I do have a healthy respect for them. I also use jigs, push sticks and other safety items.
In a previous post, one person mentioned that his father did not use the splitter or blade guard. One of the problems with older style guards and splitters is that it takes 3 to 4 minutes to take off for non-through cuts and dados and 3 to 4 minutes to put back on. When you do this several times a day or project, it becomes a time problem. So most people leave them off and accept the responsibility of personal caution. Doesn't always work, but at least they accept the responsibility.
