HMMM.. Thanks for supplying a diagram of the future folder..
I'm still leaning toward the full frame lock, it seem to be a more solid design. I have no doubts that the Busse folder will be simply amazing just like the rest of their blades. Does anyone know what the advantages and disadvantages of full frame lock and axis lock folders??
the pros
frame lock
- lot of metal behind the lock, if done properly
- very strong, IF the angle and curvature of the lock portion of the frame is done properly
- one side does not require a full liner, so it can be a bit thinner then a liner lock knife, or a lock back (depends on design though)
axis type ock
- very strong, if the spring is strong enough
- the "axis" (tm) lock itself has 2 springs, one on each side, that act as a safety should one be damaged or fail.
- ambidextrous
- very easy to operate, and creates a "gravity" type knife when the lock is disengaged. wich is to say, when the lock bar is pulled back, the knife is free swinging and
extremely fast to open (can be opened by gravity) - even without a thumbstud or flipper of any kind.
- jerries design uses one side of the scales as part of the locking mechanisms houseing, so it also does not require a liner for that side.
cons:
framelock:
- If the lock portions angle is done poorly, the lock will be unstable, potentially prone to low pressure disengagement, and may also be prone to "sticking" where it engages completely and requires a great deal of pressure to disengage.
- can be difficult to disengage if the lock portion isn't raised, lowered, or textured enough for the thumb to grip on
- not ambidextrous
- requires one of the scales to be the lock, wich can be aesthetically unplesent (if done wrong).
Axis type lock:
- if the springs are not strong enough, it can result in a weak lock up that can be prone to dissengaging.
- if the springs are made of a metal that is prone to corrosion, they can prematurely fail
-requires a spring to be present.
and I'm sure there are others that can be added to both... honestly - if either one of the types of locks are done correctly where the materials are chosen for strength, corrosion resistance, and wear resistance, and the designs are plotted out and created according to good mechanical common sense: they are both excellent locks.
I prefer the axis type lock because its easier to engage and disengage. every liner lock and frame lock I've ever used required some level of friction to occur between the pad of the thumb and the bar - a small complaint, until you have to open and close your knife for a few hours straight. I never found that to be the case with the axis type locks. I love the fact that you can open axis type lock knives so quickly, without having to push on the blade in any way. I've always found that I disliked flipper style knives because it felt like if my hands were greased, I'd be increasing the risk of it flying out of my hand by pushing on it in that manner. and thumb studs are the same situation as liner/frame locks, where friction on the thumb gets kind of old after a while. not so with the axis type locks. and they are
very fast to open.
Jerry's design isn't an axis lock (wich is property of benchmade (i think)), it's a spring operated locking bar thats of a similar theory. the axis lock uses omega springs, wich is kind of like a watches spring, where its coiled in a circle like tape, rather then like a car's shocks.
this is the rest of the patent papers that have been presented on the forums:
http://www.google.com/patents?vid=U...printsec=abstract&zoom=4&dq=7,032,315#PPP1,M1
rather then being a round cylinder like benchmades, jerries patent shows a kind of platform for lock engagement, rather then something thats round.
I wouldn't want the busse folder to be a frame/liner lock honestly, nor would I want a lock back. I've used all three and have had the least problems with the axis type lock, and prefer it all the way around. I think its a more versatile design that is easier to use on a day to day basis.
