Since Regular Sebenzas are quite old nowadays and the lockup may have moved to over 85% (on used knives) or so, sooner or later some might actually hit the opposing handle scale. Additionally, I have found at late lockup it is slightly harder to disengage the lockbar. Not sure if discussed before but I was pondering on how it can be remedied. Should you carbidize the lockbar interface? I would think not. Instead I thought of if the STOP PIN diameter was slightly larger (not sure exactly how much but testing will tell) it would push the blade down and thereby causing earlier lockup. Since it will alter the lockup it will alter the closed position as well and the detent ball might not entirely get in the lock hole. So was thinking that a very slight polishing of the area (sharpening choil area) where the stop pin touches the blade in closed position would fix that issue. Basically if all tested and done correctly you could end up with in a manner of speaking a brand new knife in terms of lockup. Anyone here with skills and/or equipment that can test this? I have contacted CRK but have not heard back yet.
