I've been using a Starrett 1/2 BiMetal 14/18V band saw blade for years. It finally snapped. No big deal, but when I went to bend it in sections so I could put it in the garbage it would snap instead of just folding over. Does this sound right. I'm not going to try it on a new one since it might do the same thing. I'm thinking that maybe over time these get brittle. Right, or wrong?
