Are you really sure that's a good price if you buy that many and use them quickly? I still buy the name brand and use them for a long time. Yes, I do a lot of cutting and they are still cutting good. It's an irritation when they start missing a thread or 2 so that's when I change the blade. I usually get one with my Jo Ann's coupon so it is a good price for as long as it lasts for me. But that's just my opinion.
