Aye, they changed the machining process a handful of times during the early stages of production - the finish, lockbar cutout, and I think even the lock geometry changed slightly a few times.
Here we go - I found a post from a ZT rep from 2012 in this thread, which I have reduced to the relevant part:
" There haven't been what I would call "generations" on the 0560/0561. but there have been a few adjustments that we have made along the way. This is pretty typical for a new product - we sometimes find little things taht we can improve as we get going with production. Below are the changes that we have made to the 0560 - they're really more subtle adjustments than large generational changes:

Back Handle - We have changed the finish a little bit, but these are pretty consistent. Some of the early ones looked darker. We also changed the lockbar cut several times. The first few were machined and you can see that the slot is wider - more like 0.060" wide. Then we started laser cutting the slot, which narrowed it down to a slim 0.012". Finally, we changed the shape of the lockbar cut itself so that the lockbar was wider toward the butt of the knife. This was done to stiffen the lockbar and combat vertical flex."
