They re-sharpen with my reg little blade sharpener and cut just as well as the 35.00 pack of 5 does. There have been several "interesting" threads on the subject...I will continue to buy and use them with my Olpha rotary cutter. The only downer for me is that they only come in the 45mg size! I can live with that! Hope this helps...at least buy one and judge for yourself!
