i have found that Columbia River knives can be a pain in the ass to reassemlbe, and have found out these things which should help you get it back together properly:



The face(good-looking part)of the knife has one white pad and nothing else on it



The back-side of the knife always has the copper washer against it first, no pad then washeer, washer-pad



On the m-16 knives, if you take the female pin and put parts on it, the o-ring is always first



Any others you guys'd like to mention?
