What blade finishes do you offer?

| 0

We originally made all our knives by machining the blade bevel, rather than grinding it (grinding is how most knives are made). This original finish, in which we polish the milled bevel but leave the machining lines is what we called our CNC finish. We are in a gradual transition to ground bevels on all our blades. The ground blades have now replaced the original finish, though we may have seconds stock in the CNC finish on some models. The first ground blade was on the Skaha knife and for it we are doing a polished stonewash finish, though other finish variations may become available. More details in the descriptions below.

CNC Finish

We then polish the bevel with various grits before and after heat treat, ending up with a bright reflective sheen. The CNC lines remain visible, adding a unique texture to the blade.

We have not been able to measure any difference in slicing performance between our CNC  finish and a typical ground knife finish. However, some customers have reported better food release with the CNC finish on the wider blades (Sitka and Alder) especially when cutting hard and wet items (eg potatoes). NOTE: except for a few remaining seconds knives, we no longer offer this original finish.

Polished Stonewash
