I've just completed my first three day Damascus chef's knife class with a student. On day one Mark made the billet and performed multiple forge welds on it to get his layer count up to 124 layers. The billet was made from 1075 + Cr high carbon tool steel, 15N20 and pure nickel. The blade was also hardened and tempered by the end of the first day. Day two consisted of grinding his blade to shape and then grinding in his primary bevels. No forging was carried out on day two because we wanted to really focus in getting the grinds perfect ready to etch the blade and reveal the pattern. By the end of day two the knife was ready to go into the coffee etch. Day three was all about the handle and Mark chose a beautiful piece of Ziricote for this which really complimented the dark patterns in the blade and the dark figuring in the wood.
