Good Morning~! I have the Tri-Sharp Dual Rotary Blade Sharpener - "sharpens 45 mm rotary cutter blades. I use them on what is left over of my old blades and also the Harbor Freight blades. My mother gave this to me and she used it for quite a while. The price tag is still on it - $15.79. Works for me! Haven't bought blades for a long time! Edie
