I fixed these issues by adding a handmade G10 scale, which also lightened the knife considerably, redrilling the detent hole in the blade to help with the weak retension and adding some titanium putty to the blade tang, just enough to clear up the lockup issue and then reground the lockbar face to be a little less shallow. I used this titanium putty trick a lot in my past life as a roboticist in repairing cracked or damaged parts. When dry, Ti putty is just like having solid welded titanium, and wears much in the same way. I then had the blade tang and lockbar carbidized to help the materials wear a bit better, so the knife is rock solid now.
Additionally I textured the entire frame in my anti-scratch finish and anodized the innards blue. This is a polished Ti finish thats totally impervious to scratching and scuffing, I think it also feels great in the hand and provides a little more grip than the standard media blast.
