Kershaw Leek opened in my pocket and stabbed me.

The spyderco on the bottom is the one that opened "by itself". It was actually hanging off my seat harness and something must have caught the hole. The delica was purchased by me from someone on 20210609_185845.jpg this board.

Neat scales on the Delica, what are they? I've had issues with keys and random pocket crap getting stuck in Spyderco holes and causing problems when I jam my hand into the pocket.

Ideally , you find the sweet spot between absolute safety and usability .

A very common complaint for Cold Steel Tri-ad lock folders is the difficulty of opening .

This problem tends to ease with normal use / breaking in, but there are also short cuts to weaken the spring .

However this will make the knife less safe and somewhat weaker overall .

Can't have the best of everything at one time . ;)

You have to accept some risk for any very easy opener , IMO .

On the other side of this, I prefer a strong detent for manual flipper and thumb stud knives. It helps to keep them closed when you want them closed. It also allows them to "snap" open more reliably and with more satisfaction. :)

A very strong detent will sometimes draw complaints. In those cases, it's worth considering issues like overall ergonomics, grip geometry, tab shape and whether it has aggressive jimping. A lot goes into getting things just right for a manual action.

I have the same preference for a strong detent as well.

Many times I have dropped a folder and it flies open due to a weak detent. Flickability is not high on my list of features for a folder.

Saying that, a quality knife should have smooth operation and tight tolerances.

I like when a knife doesn't shake out but breaks crisply with the intended opening method. I like it to snap out beautifully to a solid lock-up with only the intended opening method (no wrist movement). I also like when a knife closes by falling or gliding smoothly once past the detent but that isn't necessary for my enjoyment.

Staying closed when being dropped is a little different. Falling from pocket height to the floor can exert a lot of force. Especially in the case of tile or concrete, I wouldn't begrudge any of my knives for opening under impact.

As long as they don't open before they hit my foot ! :eek:

If they bounce, then open just right, and then hit your exposed foot; then that would be terrible. It hasn't happened to me but probably because there is a lot that needs to happen in succession. A lot of factors matter such as whether a knife is assisted or has any degree of detent strength, how far it falls, what kind of floor surface it hits, how it hits, whether or not you are wearing shoes, etc.

I guess the question is: under the chain of circumstances where this happens for a particular knife X, for which knives wouldn't it happen?

Coincidentally, a guy on another forum just got a nasty foot cut. It was a brand new assisted knife. It was probably oily. It snapped open with unexpected force and escaped his grip. It was already locked open as it fell. I think he was barefoot.

I am not a fan of assist opening knives for that reason........happened to me twice and the last time received a nasty cut reaching into my pocket.
Give me a smooth opening regular knife any day.
