My earlier description was based on a leverlock .. relative to the interaction between closed & open locking positions. Being a lockback .. this relationship will likely not exist in your buttonlock.
The sear pin relationship with it's associated "interfering surface" of the blade still exists ..and.. the fixes the same as I described.
Ken .. what you describe is an unfortunate shortcoming w/ many autos. It's referred to as "blade peeking" .. where the tip of the blade is peeking outside the frame of the knife.
.
Both Muskratman & Bill DeShivs would be capable of the repair. Both have excellent reputations. Neither will be inexpensive .. skill comes with an appropriate fee. Neither may even wish to take on the repair. While it is common .. the fix is not always easy.
.
The fix involves dis-assembly ..and therefore.. successful re-assembly. Often .. the sear pin will require peening. This is a hardened part. You can not just start "smacking" on it w/o breakage being the result.
.
The peeking issue stems from the relationship / interaction between the sear pin & associated slot in the blade itself. To further complicate, there's also interaction with the frame.
.
A worn sear pin surface could & would cause the locking action to occur when the knife is (quite unfortunately) slightly open ..hence.. the blade tip peeks outside the safe confines of the frame. Material could be added to the sear pin ..or.. peening could be implemented to change the profile of the sear pin ..BUT.. replacement is a far more realistic approach.
.
It should be noted .. whatever is implemented to effect the closed locking position has the high likelihood of effecting the open locking position. This type of repair really should be left in the hands of experience. Experience that has exposed & taught the subtle interactions between the 2 locking positions.
Thanks for joining our "Knife Repair, Modification, Restoration & Improvement" group. There's a good group of folks there .. collectively yrs & yrs of experience .. got a question .. pose it to the group & someone will step up to the plate. Enjoy the day !!! D ale

Ken .. I just re-read your original post.

Got a pic by chance ???
