My Sage 2, Techno and Southard all have terrific detents and action after over a year of owning each of them.
On the other hand, I stopped carrying my Bradley 1 when the ball detent ball had worn flat enough that the blade could be shaken open pretty easily.
My current favorite EDC is my Mantra 1, but I can't help noticing that the action has degraded pretty significantly over time. I can happily accept some "mushiness" developing as part of using a knife, but was curious if some models are more prone to detent ball wear than others?
The three Ti Framelocks, despite being owned longer, have held up much better than the Mantra and Bradley. Could the detent balls on the titanium locks be performing better than those on steel inserts/locks for some reason?
Would the higher hardness of M4 result in wearing balls down faster than XHP or S30v?
Anyone else have experience with particularly long-lasting or short-lived detent quality?
Has anyone had a knife-maker/modder install a ceramic detent ball into a framelock or linerlock spydie?
As a side note: My current Mantra is actually a replacement from W&R (who rocked
) because my first's detent ball pretty suddenly failed within 3 weeks of purchasing. A total fluke, but it's got me thinking about detent wear as a factor in choosing locks in the future.
