I am seeing a few knives for sale with replaced or upgraded thumb studs. How is this even done, as I understood that the studs were pressed in during the mfg process? Also, does doing so void the warranty?
 
Voids warranty on the blade if they are aftermarket. The lugs are press fit (interference fit) so if the size isn't exactly right there's a risk of stressing/cracking the blade. Of course you can get a new blade from CRK (for cost and the wait).
 
I had mine replaced by REK I'm not to concerned about the warranty on the blade because the new thumbstud makes the knife just about perfect
