Scrappile, to answer your question all you have to do is read what I wrote. I never said anything regarding "worn out" blades. I clearly wrote that a blade that was being used but still having life left in it, how do you keep track of what it is, size, tooth configuration, etc. so that you can save it for when you come back to the project you were working on when you changed to something else. I realize they are pretty cheap but so am I. I throw away the ones that have become dull or show signs of heating up. They go into the can. But, why throw away a blade that still has a lot of life left in it? That's all I'm asking and how best to keep them organized?
