Mine we not skipping a few threads, but at least 1/4" or more. I could live with a few threads, but not this much. At least the third pkg. of blades is GOOD and I'll get rid of the bad ones. Having a blade skip kind of slowed down my cutting. It's all fixed now and feels better,lol! I sure didn't want to pass along any bad product to my SQA or my DM! I guess you get what you pay for, but at the inexpensive price I'm doing pretty good with the ones I still have to use and surely it's enough for a very long time.
