What knife do you think is stronger ? Lockback or Frame lock ? Does the geometry for the frame lock essentially weaken that side of the knife ?
 
It all depends on how well the rest of the knife is put together. I'd go with a well-built framelock any day.
 
I agree with gooeytek. I think a week liner or poorly made liner can ruin a well made knife. Id choose my titanium framelocks all day!!
 
Moved from General Knife Discussion to Shop Talk.
All you will get in General is opinion, in Shop Talk you can get expertise.
 
I'd go framelock as well. My lock preferences:

Spyderco's Ball Bearing Lock
Compression lock
Framelock
Axis Lock
Back lock/lockback
Linerlock

Most are made with titanium, and it is definitely strong enough.

Are you asking about the lock's resistance to closure or the strength of the scales that use used in making each lock? For example, say you have a lockback with titanium scales, and a frame lock built using the same titanium scales. The scale on the frame lock is going to be weaker because it is not solid. It has the lock bar.

I don't believe that weakness has anything to do with the strength or weakness of the lock though.
 
The Framelock appears to have more contact surface with the back of blade tang. I wonder if it could survive a Triad style test ?

So again, are you asking about the lock's resistance to closure or the strength of the scales that are used in making each lock? Scale failure doesn't cause lock failure.
 
A framelock really has very little contact with the blade
Not that that has any influence on overall lock strength.
You could be using 1/4" Ti and have total engagement but the Ti has to be relieved in order to make a lock that functions for a human being.
Thats usually going to be the weak point.
 
marcinek,
The Triad lock test specifically measures it's ability to keep the blade locked open when loaded. I and many other's think it's a very valuable and valid lock test and

currently the Heavy weight champ. What is your opinion of the Triad style test ? Why shouldn't it be valid for a Frame lock ? Shouldn't a beefy frame lock be able to handle

the same load ?
 
The Triad is the strongest out there IMO, but I and most all others will never need anything stronger than an RIL.
I like lock-backs, but don't care for the Triad at all. The one's I have seen(CS, I haven't seen custom Demko) had a lock that was harder to depress than I like. It's not all about lock strength.

Who said all knives were to be created equal?
The question for any lock should be 'Shouldnt x lock be able to handle the load that any reasonable person would apply to it'

Cant you create a computer model to answer these questions for you?
 
FTO_dude,
You say......"The question for any lock should be 'Shouldn't x lock be able to handle the load that any reasonable person would apply to it'..... So you are

implying that the Triad test means nothing ?
 
I've never even had a slip joint close on me. Maybe I've been doing something wrong with my knives, but I've got to get with the program and get to getting some failures with my locks. I'll try and post some pics once I get finished using my blades backwards.
 
All design is tradeoffs.

The Triad is a very strong lock. It's also a bit clunky and not as convenient as a liner or frame lock. Everything has its use. I wouldn't hesitate to carry a triad lock if I was in the habit of hanging weights from my folding knife or thought I'd be using it as an emergency piton from time to time. For me it's overkill.

Every person will have a different set of priorities. That's why there's no one true holy grail of locking mechanisms.
 
i feel like im trying to be entrapped in some sort of logic spiral that somehow proves the FFKs lateral strength nonsense to be somehow relevant.

'Triad test' proves the triad lock is capable of withstanding large amounts of weight being hung from the knife.
if thats the only concern you have in a knife then by all means its your winner.
But I find a framelock or liner lock more pleasant, easier and quicker to use. And you can make them flippers.

'My Chevy can tow 10,000lbs. I and many other's think it's a very valuable and valid test and its currently the Heavy weight champ. Why shouldn't it be valid for a Mazda? Shouldn't a Mazda be able to handle the same load?'
