This is an excellent sharpener for most knives but is different from other Chefs Choice models. Unless you have PEtec knives, the sharpener put a completely new edge you can see because it extends up the side of the blade by about 1/16th or more. Not much but it is reshaping the blade. this is great...

The short answer is yes, they will be very sharp. But you will have to spend a lot of time on step one, the most aggessive sharpening stage that removes the most material from the blade creating an entirely new shape to the cutting edge of the blade. If it is a PEtec blade you would probably not even need this stage, just go to stage 2 since you already have the proper shape. The problem is other knives have a different design for the blade edge and you are grinding that away. The edge may have been cut and hardened using lasers and carefully engineered for optimal sharpness and sharp longevity. When you grind the design away to get the PEtec edge you may well be into softer material than the original edge. Most European knives like Henckles and Wustof were set with the Trizor edge, a 20 degree edge designed for 20 degree sharpness, not the 15 degree sharpness of the PEtec. The difference can maybe be felt by an experienced chef or knife expert. 15 degrees is sharper but loses it's edge sooner. Most Asian knives like Shun and Global are 15 degree. The PEtec is probably the first Euro/American knife designed and hardened for the 15 degree edge. To sum it up, the new edge will be sharp but may not stay sharp very long because you have ground away the manufacturer's edge and the hardened steel. If you have an Asian knife, same problem. You put a new shape 15 degree edge on it but ground away the designed and hardened edge, A better bet is the Chefs Choice 315s for Asian and the 120 for Euro. The Trizer edge is 20 degree but will not need to be sharpened as often. The 315s will sharpen 15 degree Asian knives without grinding the original edge away.
