This is my 83 from the 2015 run. The lock is pretty solid with no vertical play, but
slight play side to side. I also have a 99 lock back, and a 72 lock back. Both of those have play side to side and vertical . This 83 has the most solid lock up of any GEC lock back in my collection. Disengaging the lock is a bit more challenging too...
This particular example is my favorite jigged bone pattern of any GEC that I own. Having said that, the 83 frame is probably my least favorite frame. I think I would like it much better if it were a slip joint. The lock back on such a diminutive knife is out of place IMO. Different strokes for different folks. I don’t intend to chase after the upcoming release - good luck to the rest of you 83 fans hot on the scent.
