I bought the TruCut Electric Blade Sharpener that is currently $64.95 on their website. It is great. Haven't bought new blades in forever. I do what was suggested earlier sharpen them for 30 seconds as soon as they start acting a little dull. What I paid for in the sharpener I have saved many times over in blades. Also check out their rulers and cutters while on their site. They also are one of the best purchases we have made. We have them all.
