As far as we are aware these are the first cryogenically treated hook knives available worldwide.

The hook knives get treated with liquid nitrogen to slowly lower the temperature, homogenising the crystalline structure of the steel. Objective scientific testing shows that the tool steel that we use will offer greatly improved edge retention. From our tests the tools hold an edge exceptionally well, and they do not feel any harder to sharpen.

We are offering them in all of our standard blade curvatures, see more about the compound curve and the open curve.
