Pros = cons to early or late lock up

On a frame lock.

I would say that the pro would be that there is a lot of room for wear, meaning that it will last a long time.

Con= might slip off and you could loose a couple of fingers.

I used to be a fan of early lockup, but after owning a Sebenza and Strider my thoughts have changed. Some like Mayo's look way too early and scarry

The general consensus around these parts is that early lockup is better than late lockup. This is because you have more room for wear and in theory get longer life out of the knife. The con to early lockup is that not as much of the lockface is contacting the tang. This does not necessarily mean less strength and reliability though. Framelocks look incredibly simple and similar however they can be and are made very different from eachother. There are all sorts of variables that factor into strength and reliability. For example angle of the lockface as compared to the tang face, is the tang face flat or semi circular, what kind of cutout does the lockbar have(inside cutout/outside cutout/thick/thin). However there is really no set formula as to what combination works best. It really comes down to the processes taken to make it and the attention to detail... and a bit of luck. Titanium framelocks are my favorite platform of knife and I count myself lucky to have had the pleasure to own and use to many. However in buying, selling and using my share of them I have come to find out that sometimes you get a perfect framelock with vault like lockup, ease of use and slow wear and other times you don't get as lucky.

If I had to claim a few features of framelocks that I generally prefer to see I would say a semi circular blade tang face, a thick slab of ti with a cutout large enough to make it easy to close but keep the strength to a maximum, and a slightly angled lockbar face to fit on the tang face with more surface area(such as on the Buck TNT). I know I got a bit of topic there but I hope this helps.

Early no Late no. 50-60% YES. With a CRK or a Strider or any other high

end frame lock the lockbar isnt going to move from where it is when its new.

Thats why I say 50-60% or a little more is just about perfect IMO.

Buy a Quality frame lock and you wont have any worries about a lockbar

moving

I have no idea what you are trying to ask??? No offense but if you want a good answer spend a couple minutes making a legible post otherwise people will usually just hit 'back' and move on.

If you dont have a frame lock knife you wouldnt understand.

The SmF I use the most has moved quite a bit.
The Spyderco Titanium Military I sold to my brother moved from 70% lock-up to 90% within one week.
My Emerson CQC-12 went from 50% to 90% lock-up in 2 weeks. I had another which did the same thing.
Given my experiences, I cry foul on the idea that a quality frame-lock will not change in its engagement.

He's asking for the pros and cons for early or late lockup on framelocks.

You sure your posting in the right thread? It's clear to me anyways.

Sorry Stabman I based my statements of lockbar lockup on my knives....

an SMF, a few CRKs, and a few others. I dont understand why a lockbar

would move as much as a couple of yours have in a very short time.

Quite unusual

espeically in a Ti millie and a cqc 12 and an SMF...sounds like you have

had a bad luck with a few quality frame locks.

What I noticed on the Military and the CQC-12's was that initially the contact point of the lockbar was, well, pretty much a point; it was very small. This allowed for greatly accelerated wear initially, which has seemed to slow down, thankfully, as the contact area is larger now.
The extremely ramped nature of the SmF tang makes me think that it has probably reached as far over as it's likely to travel for a while (keeping fingers crossed).
With the "point style" nature of the lock interface though, these knives SHOULD have been shipped with about 10% initial engagement; even after wearing in then, there'd still be plenty of room left.
I don't like to use my remaining CQC-12 very hard now, as I'd like to keep it from touching the other side (I don't want to have to send it in for repair, especially as the repair most often done seems to be peening the lock-bar).

Pros=cons to early or late lockup on a frame lock

Nope. Still doesn't make any since to me. Guess I'm missing something if everyone else understands. That or I didn't get the decoder ring.

I could take a guess at what he is trying to ask but it is far from 'clear'.

 

[Leonwood]

We all understood what he was asking, what part threw you? What the op was asking refered to optimal lock bar interface with the blade tang, and how a convex or concave bladetang grind and rockwell hardness of titanium hardened lock bar will influance lockup and wear coeficiant. Its all very simple.

LOL. That's funny. I guess I see it now that you mention it. Oh well, forget I said anything.

The earlier the better on a TI frame lock for me. At least after the minimum point of good lockup. If I'm forced to give up number, 25% OOTB is a good figure for me to be delighted with. Why? Length of safe, useful life of course.

 

[Leonwood]

On a sebenza for example the Ti is hardened, so wear is nil, so a good 60% Lock up is good. I used to love real early lock up, but ive read stories of disengagement and cut fingers., so 50 plus is cool.
