Spyderco returned my call today about the KJ 2nd gen. Slysz Bowie pivot. The gentleman was very brusque... And almost seemed annoyed with me? I was a little bewildered as I thought the message I had left was very respectful.
First he informed me that he didn't think there had been any changes to the pivot of KnifeJoy exclusive Slysz Bowie 1st gen and 2nd gen release. I informed him that I had both a 1st gen release, and a 2nd gen release both on hand and that the pivot seemed to be much more shallow on the second gen (which others have also reported), and that there are also reports of red/permeant loctite being used. Then he questioned me about why I, or anyone else would want to take the knife apart to begin with. I let him know I like to replace the lube with KPL.
In the end he told me to send the knife in. I asked specifically if the pivot could be removed and replaced with a new one and was told yes... So it sounds like they can help. I'm glad I won't have to resort to destructive means and replacing the pivot.
When I got off the phone I wanted to make sure I wasn't crazy, so I measured the pivot depth of both knives with a set of Mitutoyo calipers. On the 1st gen. KJ release I get a repeatable depth of .235". On the 2nd gen. KJ release I get a repeatable depth of .017".
I think this video shows off the issue much better though. The first bit is a Wiha T8 Torx. The second bit is a higher end, PB Swiss T8 Torx. The first gen is on the left, and the second gen is on the right.
