Introducing Edlund's factory precise Model 401 Electric Knife Sharpener. The 401 was designed with the input of engineers from the market leader of professional cutlery. The result: a sharpener that recreates a factory fresh knife and maintains the integrity of the entire edge, tip to handle. The blade is not merely sharpened; it's restored teach time as if the knife were new. Another sharp idea from Edlund, of course!
