Today I finished my first full integral knife. I first milled it with my milling machine roughly from a 7mm thick piece of Niolox steel and then I formed the contour on the belt sander.
The handles are made of Gagat. This is a form of petrified charcoal. The material is relatively poorly workable, as it gets cracks very quickly. After putting everything together, I polished the knife and made it extremely sharp. ;D
