I know my lockbar insert showed pretty significant wear early on. It started taking to the shape / angle of the tang. Whether that is by design during Hinderer’s development of the knife is anybody’s guess. The more worn the insert got, the consistently worse the lock stick became.I’m just guessing here, but I have a feeling that the lock bar inserts on the M390 Full Tracks are too soft and end up galling. Anyone know if lock bar inserts are usually hardened then tempered back to softer than the blade? Maybe the hardening and tempering process was botched.
Tzoid, please keep up posted on how your Full Track holds up after a trip back to the ranch. Maybe I’ll give it one more a try after it’s been out for a year and the kinks are worked out. I really love the design, but I’m still too frustrated to go for round three right now.
So yeah, you might be on to something. But, if the majority of the issues are the M390 runs, seems like a defective insert would’ve been used across a much broader run - not just the M390s. Who knows.
