I'm thinking the chain should be enclosed or have a shield of some kind.

I've read about similar knives in the past & have always been on the lookout for one.

By similar .. I mean .. same method of deployment. However .. a cable (instead of chain) was implemented in the ones I've read about ..but.. never seen.

I've also read of ones that have a "rack & pinion" opening mechanism where the butt end of the knife was drawn back to open the knife blade. There existed gear teeth in the equivalent of the back spring & matching gear teeth in the tang of the blade. As the butt end of the knife was drawn back .. the gear teeth of the back spring caused the blade to swing open.

My thoughts ...

Really cool .. definite attention getter ..but.. manufacturing nightmare !!!

..further..

As John mentioned .. without a guard of some nature there exists no prevention of foreign objects "gumming up" the mechanism. Therefor .. I would expect a high failure rate .. Re: proper unimpeded opening.

I dunno. I've looked at this a half a dozen times or so. Other than the novelty, no ... uniqueness of the knife, still ask myself why. Uniqueness is sometimes a nice thing. I mean, Grant and Gavin Hawk's locking mechanism on the CRK TiLock is neat. Not necessarily the strongest lock, but shows design innovation. In this case, as been already mentioned, I can't imagine that chain not being constantly clogged with pocket material!! In my pocket, it definitely would. And, those knives are not light. The smallest model weighs in at just over 6 ounces. Larger ones come in over 7 ounces. Also, should mention (not that it has anything to do with the chain), but these models do not have a opening lock. The manufacturer relies on the deployment button being recessed to preclude unintended opening.

Let me amend my previous a little. The weight's I mentioned were for the copper handled versions. Aluminum versions are somewhat lighter ... in the 3 ounce range.

The chain is pulled by extension springs, it's just working in tension like a cable so I don't think pocket lint would really affect it much, there aren't any sprockets engaging the chain. So it's probably reasonably reliable but it's a pretty bulky mechanism. An enclosed cable could probably be much smaller, lighter and simpler.

I agree in the uniqueness and that is not a bad thing. New designs intrigue me, who looks at their knife and thinks...hmmm a chain would work well there! but then again who was the first one to think a muskrat with the same blade at both ends was going to last forever? Can you think of a specific need for a knife like this one?
