>>90217503poking around aliexpress "copper damascus" blanks (that's just the blade, not the handle, unclear if it's sharpened) go for $40-70, obviously a fraction of what the knife costs but considerably more than the regular "damascus" blades (this is all about style in both cases, the pattern is just welded on and ground and has nothing to do with the material at the cutting edge)
The KKKnife looks like they specified a custom weld/grind pattern as well as the notches in the top of the blade, so that would drive up the cost, while a volume discount might bring it back down somewhat. Obviously you're paying a steep markup in the end but the production costs are also relatively high, as opposed to say the SuperGroupies watch
