I posted this over on the Spyderco Forums. I figured I'd post it here for those who don't get over there.
....Particularly ball detents. I see this subject discussed quite a bit. It's definitely something I pay attention to when I get a new knife.
Recently, in one of the Sliverax threads, someone asked if the Sliverax has a strong detent. Another member responded that he thinks the detent's comparable to a PM2. So I compared my Sliverax one of my PM2s (S30V/DLC) and they did feel similar. Then I compared the SA to my PM2 Cruwear, which has a noticeably strong detent, and the latter was the obvious winner. So then I started wondering how I could actually measure the difference in detent strength of the various models I have. It occurred to me that I could use one of my most used tools from my other favorite hobby, shooting. So I got out my trusty trigger pull gauge and started doing some testing. I thought some of you might be interested in seeing the results.
Keep in mind that these are only the results for my particular knives. Detent strength definitely does vary from knife to knife as I think the results show. If you happen to have a trigger pull gauge or a similar way to measure detent strength please feel free to share your results. I think it would be interesting to compare.
Also, while this test was hardly a scientific test, I did my best to be as consistent as possibe when checking each model. I held the closed knife in my left hand with pivot facing down. Then I hooked the arm of the trigger pull gauge through the Spydie hole, tightened things up until I had a pre-load of about 8 oz, and then I pulled with gradual pressure until the detent broke and blade opened. I measured each knife several times. I was surprised by how consistent the detent broke on each model.
The results below are in the order that I tested each model.
Sliverax - 17 oz
Paramilitary 2 S30V/DLC - 20 oz
Paramilitary 2 Cruwear- 36 oz
Para 3 S30V - 22 oz
Para 3 Cruwear - 24 oz
Mantra - 14 oz
Sage 1 - 22 oz
Sage 2 - 20 oz
Sage 5 - 20 oz
Gayle Bradley (#1) - 22 oz
Gayle Bradley (#2) - 22 oz
Cat (440C) - 17 oz
Firefly - 33 oz
Some knives without detent ball just for fun:
Manix 2 LW S110V - 24 oz
Manix 2 LW XHP - 26 oz
Manix 2 LW BD1 (black) - 23 oz
Manix 2 LW BD1 (translucent blue) - 31 oz
Manix 2 G10 S30V - 23
Sage 3 - 8 oz
I thought the results for the Sage 3 were interesting, I knew the detent was light but I was surprised that it was only 8 oz.
