So far I've found that the Model Master blades are the sharpest. Does anyone know of a better source for better blades at a good price?
These blades are double honed for a strong edge and provide precise cuts every time. The included tube safely stores blades not in use. Included is (10) #11 Hobby Blades and (1) Storage Tube.
