I paid over $11.00 yesterday for ONE 45 rotary blade at Michaels. I could not believe the price increase. I went online and ordered 3 pks from HF. Lowes and Home Depot don't sell them in this area. Thought I would give it a try. I also purchased a Pinking Rotary Blade, don't know how that one is going to work. Anyway, with all the pros and cons about this thread, I thought I would give HF a try.
