The ZT 0357 is one of my favorite knives. I had the same knife in the Blackwash version (Ser # 10xx) for a while and liked it so much I wanted it in the Stonewash version too. I was pleasantly surprised to see a few upgrades on this one (Ser # 32xx). The pocket clip has been altered to allow it to easily slip past the screws and sit full deep carry. The liner lock bar in not as scalloped and now allows my thump to more easily release the lock and it is noticeably thinner behind the edge than my older Blackwash version. Could it be that ZT are listening to their customers? Wowsers!!
