So all of a sudden my knife has no retention when closed:


I'm afraid it might be half open when I don't want it to.

I can't figure out why. After noticing this I gave it a detailed cleaning and it did not help. I can't see what in the design is supposed to keep it retained either. But it did retain very well in the past.

Can anyone shed some light on this?

Hi Blan,

You must have a lint buildup or something in the close-detent area. Open the blade and look at the base with the edge facing you. See where the cutting edge stops, drops down into the handle and then you have the base of the blade which is rounded and rides on the lock bar? If you look closely, the depression area looks like a 'J'. This crook in the 'J' is where the lock bar hooks into to keep the blade closed. I'll bet you have a buildup in the crook, which prevents the lock bar from keeping the blade closed. I noticed in your video that your lock bar doesn't look like it is forward enough when the blade is closed.

Hope this helps,
Mike
 
Mike, as I said in my original post I cleaned the knife out completely there is not one spec of dust. The lock does slide all the way up. It must've been the angle of the video..


Thanks for the reply.

Yeah, I read that but it happened to me. I thougt mine was clean but the grey/black gunk in the crook was well hidden (to me). It stays closed great now that I took a Q-tip to the crook.

Good luck, hope you find your issue.

I hope so too as I was using this knife as a regular EDC.
What I find ironic is that Benchmade describes this lock as follows:

ROLLING LOCK® WITH INDRAFT® Another patented Benchmade exclusive, the Rolling Lock utilizes a sizable, notched lock-pin, which secures against the blade tang when engaged. To disengage, a spring actuated thumb button on the right handle side is drawn back to rotate the lock pin and free the blade. InDraft is a patented exclusive, which is a combination of a slotted liner and a pin in the blade tang working in tandem to generate an inward inertia when closing the blade. These results in one of the safest blade detents available today.

Clearly, this is not the case and the detent is failing in my knife.

Oops :o I was thinking you had the barrage which is an axis lock. I know nothing about the "rolling lock with indraft". Sorry for the misinformation.
