Question for CRK

This is kind of a spin off from the CR edc thread. I was wondering if CRK has done any testing on the longevity of the Sebenzas lock. How many times can the lock be flexed into the open and closed position without compromising the structure of the Ti. Does it weaken a little / alot or not at all. Have they done any controlled testing? Just being curious. I have several Sebbies from '99 - 2000 and really can't tell if there is a difference from when they were new.
 
Good question, Proguide. It will be interesting to see any test data that is available. I sure love the simplicity of the lock design. (And apparent simplicity can be the result of great engineering and sophistication...don't you agree??).

:)
 
It would be interesting to submit one for testing to see just how much it will withstand.

1. How much pressure on the blade is required to make the lock fail?

2. How many open/lock/close cycles it takes to wear the lock to the danger point?

3. How much lateral pressure the knife can take before something deforms or breaks?

4. etc.
 
I do know, from experience, that if you PUSH the lock deeper by squeezing the lock that it will move over to the other side more quickly. But you shouldn't do that.

.
 
I don't necessarily mean lock strength as I have never had a problem with a Sebenza. I'm wondering about the life expectancy of the bend in the Ti when cycled 1000's of times.
 
Good read thanks. I know the lock face is heat treated. It would be interesting to know about the handle slabs.
 
I know that titanium treated in certain ways doesn't handle any flexing and generally breaks similar to D2 steel. I assume that CRK does special tempering treatments that allow the Ti to flex repeatedly.
 
A few years back there was a full suspension mountain bike available (it still could be but I haven't looked lately). It had a titanium frame and cost around $6000. For the rear suspension, the bike didn't have a rear shock. The suspension was achieved by flexing the titatium frame. I think the rear suspension had 3 or 4 inches of travel. If a titamium bike frame can handle that sort of load cycling, the sebenza lock should never have an issue.

ti is pretty good stuff ..i notice all the frame locks i see are made of ti...personally i have flicked the hell out of my favorite sebenza hundreds of times....i had i converted to a d/a and im always playin with it...nothin cooler than a d/a...when you bead blast them they spark like hell....i think its pretty safe to say they wont wear out and if they do i think the shop would repair or replace it.
