99% of all lock up pics are around 60%. To nail the same spot time and time again seems pretty hard to do. I was wondering if he sets the blades in a jig to grind the tang to meet the lock bar. I know if i had to grind a tang one would be 10% the next one would be 95%, id be all over the board. Let me know what you think , free hand or jig?

CRK custom fits each blade to the lockbar on a particular slab to insure the lock-up is tight. I sent a knife in for warranty work that had almost 100% travel across the lock-up and they replaced the blade as part of the repair. Amazing service.
I can't comment on the technical means and methods they use in this process tho.

It may be more cost-effective and more practical to simply replace the blade with more of a blade tang ramp than to replace the ti locking handle slab.
I talked with Chris about this once, and he said the locking bar's wearing across is not as big a problem as people perceive. He also said, and this is important to note as it applies to all liner-locking and frame-locking knives, you cannot simply replace a stop pin sleeve with a larger one to "reset the lock" interface, as it were. Doing so would throw off the angle at which the locking bar meets the blade tang ramp, which makes sense when you think about it.
I used to worry about long-term wear of Sebenza's, but what I started doing long ago (to use a term coined by another forum member recently) was to "soft-set" my lockup during opening, opening normally with my thumb against the lug until a little over halfway open, then using my forefinger against the back of the blade where the thumb ramp serrations are to open the blade the rest of the way while "dampening" the engagement of the lockbar agaist the blade tang ramp with my thumb at the same time. With practice, you can do it just as fast as opening all the way with your thumb. Once open, simply squeezing in a normal forward grip will engage the lock fully and safely.
While it may seem nuts, it has caused my lockup engagement to be the same (right at 65%) on my edc small Seb for over eight years now.
I do tend to overthink things, though. YMMV!

CRK custom fits each blade to the lockbar. The CRK DVD which I Highly Recommend shows this. It looks like a tedious precision operation, but this attention to detail is what makes CRK The Best Knives In The World. The DVD shows the sebenzas through the whole mfg. process and will answer Many Questions that members ask. Its a 2 disc set and was well worth the price. One disc is the sebenza and mnandi, the other disc is the one piece knives ( now discontinued ).
