Honestly, from my perspective, if the lock bar is almost touching the other side of the scale, then either the blade or the lock bar side scale has to be replaced. It seems that too much material was removed from either of these two components either by CRK or by the owner. I guess this could be caused by forcing the lock bar past its engineered stopping point causing a deformity of the lock bar side of the scale. This is unlikely given the properties of the Ti scale .
I recently took one of my sebs in to have the blade replaced as I didn't like the angle of the edge. I was told that it would take some time because of the frequency in which they make the serrated blades and I would receive a call when I could bring the Seb in for the transplant. Less than a week later, I had a new blade! The response from CRK is nothing short of spectacular! I am just sad that I live less than 5 miles from the CRK shop...restraint is difficult!
