> I've always heard that a sharp tool is a safe tool. I absolutely agree with that statement. If you don't have to force a cutting tool, you have more control over it and hence less likely to have a mishap. However, if you are going to have a mishap - and blade meets flesh - be aware that a sharp tool will make a much larger and deeper cut than a dull tool - although on a positive note I suppose the larger and deeper cut will be smoother and less irregular - I presume surgeons prefer it that way.....
