Ricassos are the hump at base of the blade. I can find nothing in my notes about having seen a Krebs Damascus piece. Most Damascus pieces I have seen and all I own but for the Horster HJ do not have a maker mark on the blade. I know SA and SS Damacus blades often have the Eickhorn maker mark.
In a knife collecting magazine I read about a year ago there was an advertisement from a damascus smith on the US east coast who would make a blade to your custom specificiations. They continue to make what they call Damascus and Boker, Case and individual smiths are making Damascus pocket knives and hunting knives for collectors. These are mechanized drop forge blades so the literature says. I have Case, Boker and Parker Damascus pocket knives and none of the patters resemble the 3R patterns I know. Ruxx
