I highly recommend the electric TruCut sharpening system. I am able to keep my blades sharp and have not purchased any new blades since I got it. It only takes about 20 - 30 seconds to restore a blade that is just not cutting well. No more using blades until I have to press so hard it hurts my wrist. I also love their rulers with the ridge and the ergonomic cutter that rides on the ridge so the blade doesn't wobble as we cut and we are more accurate.
