I dropped my Spyderco Tenacious, and it snapped open. Is this usual or indicative of detent wear or something.

Thanks!

Depending on how it landed this might or might not indicate a problem. You can tell when you open the blade yourself if it has sufficient detent or not.

I've been carrying linerlock knives for nearly 20 years and back then they didn't feel the need to have a lot of detent. I've noticed that newer knives have more detent, and assisted opening knives have a lot more. In fact the extra detent with assisted opening knives seems to me to defeat the purpose and most of my non-assisted knives can be opened quicker than my assisted knives because of the difference in detent.

I have a couple of new Tenacious knives and they both have more than average detent, certainly more than I think is necessary. In normal use I don't think you need much detent. Dropping the knife on the floor doesn't count as normal use.
 
Thanks for the reply. I was just wondering, because i've dropped other "cheap" knives and they didn't pop open. I think it's because of it's smoother opening action compared to the other blades.

I'm sure it was just the way it landed. Prolly at an angle right around the spydie hole causing a spring type action to throw the blade open.
 
I've had mine partially open a few times. It depends how it hits the floor. Tightening up the pivot a little will help. Not a big deal to me.

I have the resilience, and it too has a very weak detent. The blade can easily be shaken out, but I don't think that it's necessarily defective. I don't see it as being a safety concern. That's just the nature of some liner locks. And obviously, the tenacious series.
 
My Tenacious has been on my desk all night before and never opened by itself.
 
Other knives do this as well. Early Tenacious models had weak detent, that's been solved, but I've had more than 1 linerlock open when hitting the floor. I guess the kinetic energy somehow transfers into the thumbstud or Spyderhole. :D
 
Even some axis or back lock can open if dropped correctly ;)
I have some that did, resulting in edge or tip getting chipped or rolled hitting the tile, albeit at an angle (not 90 degree frontal). I do keep my edges thin.
 
My Resilience and even my Millie have opened when I dropped them. Both are well broken in and I've never adjusted them (nor do I plan to). Perhaps tightening the pivot would help?
 
It happens to me all the time with a whole wack of different knives. I don't think it's an indication of any kind of fault with the knife itself.
