Here's a picture of my 3 Heinz Kocher knives. I don't know much about this maker, but I do know that they are some of the most nicely fitted and finished knives I've seen. All 3 have some kind of "assisted opening" mechanism, that makes the blade open a little bit. All 3 mechanism are different. This man is a technical genius! Handle material on the top one is Desert Ironwood, on the bottom one Mother of Pearl, on the middle one "Katec".
