I was cutting and the blade started to get bouncy and bangy. It was not cutting worth a darn so I hit it with a grinding wheel and it cut about 2 mm in and stopped. Now I know what is up. I turned it off ans sure enough, the diamonds were all gone. I have never actually wore one down to the nub before. I usually foul them up or think they are done for. Now I will have to go through the stash of old blades that I never tossed out and see if there are good ones in there. I never knew the grinding wheel trick early on.
