Yojimbo lock question

[Zedd]

Hi!
I now own a Spyderco Yojimbo (GREAT knife!!!!) and have the 'feeling' that the 'lock-back-bar' is a little thin :grumpy:
Anyone having any trouble (unwanted collapsing...) with it??

Best Regards,

Zedd

Love the knife...I have had no problems with the lock so far.

While I personally like thicker material for locks, I don't think that will be an issue with this knife. It should stand up to as much abuse as you could expect a small folder to handle.

It's not like a massive frame lock, but the spring is actually a little bit thicker than some liner locks. I'm sure it'll be fine. Very nice knife, BTW!

The thing to remember is that the way the compression lock works, for the lock bar to fail it would have to be crushed, not slip like on a liner lock. I don't think the lock bar itself would ever fail, rather I think the failure on the Para actually be the stop pin being ripped out of the steel liners.

The compression lock wedges the tang agaisnt the stop pin as opposed to the liner itself blocking it out

Its MBC rated, so als long as you haven't gotten a faulty knife it has a lock that is among the strongest in all the land.

As a matter of fact, the delay in the Yo coming to market was that the initial prototypes did not achieve MBC rating (over 200 pounds per inch bladelength), but Spyderco changed the liner steel and that problem was taken care of. Which means that the Yo will not buckle under 600 pounds one inch from the hilt (which is actually kind of difficult to achieve, given the blade shape).

Keith: Actually, Sal meantioned in one post that the compression lock is currently designed such that the lock bar is indeed the "weak" point of the system, but that is an intended design parameter. The lockbar will eventually deform and torque before the anvil pin gets torn out of the liner.
