Fall Shut Action Folders

Little tough to see in the video, but I was holding the MILK at a angle (side to side, as in laying towards the lock side) and slowly raising it towards straight. Held straight vertical, if immediately falls.

I mean none of these are still really free fall gravity only shut you know.

It's bigger than you want, but the Buck Marksman does this. It's not because the blade is heavy, it's because once unlocked the lock doesn't make any contact with the blade and it is on bearings.

Edit: I see this was already mentioned. It is super frictionless if that is what you want. I agree with the other poster about it bouncing around if you slightly misflip it (or don't close it hard enough), but it's still a pretty neat knife.

Agree with above. Most ball bearing framelocks will fall shut as long as you hold the lockbar (and thus the detent ball) off the blade.

Does that really count? It won't fall shut with your finger there...unless it's wickedly sharp. :eek:
 
Surprisingly my Byrd Cara Cara with frn scales has very smooth drop shut action.
Back locks, axis, and compression are the best locks for this trick.

As long as you know to keep fingers out of the way or can keep your digits where the choil drops it can be a nice feature for one hand closing.

I think though for liner and frame locks true fall shut where you don’t give the knife a little shake is less common to see. Especially on knives with smaller lighter blades. The detent pushing against the side of the tang will provide enough friction to prevent a true fall shut.

Though I run my bearings knives dry. Maybe a little lube on the knife and detent ball will promote better fall shut action on liner/framelock knives.

Only my Shiro 95T and my North Arm Skaha truly fall shut with the lockbar against the blade tang. My NeOn Ultra-Lite falls almost to the detent ball and just stops short and I've got a couple others that are close. I often put a little blob of FinishLine on the detent ball to grease the skid, so to speak.

Drop-shuttiness is kinda cool, but hardly a necessary or useful feature in a frame- or liner-lock knife. I just want 'em free enough so I can forefinger-flick 'em closed. :cool:

On frame- and liner-locks I consider it dangerous.

That’s what I do. Unlock, close just enough that the detent ball is resting against the corner of the tang but hasn’t yet jumped up on the side of it. Now the blade is unlocked but being held open by the detent ball. A very slight touch on the spine of the knife causes the blade to slam shut.

Although after seeing how flattened the detent ball is on a used Emerson framelock I got I am no longer resting the tang on the detent ball then pushing it shut. Now I unlock, close the knife far enough that when I release the lockbar the ball is now on the side of the tang. The friction keeps the blade mostly open. Once again a little touch to the spine of the knife causes the blade to slam shut.
