I just received an older but NIB Sebenza large and I noticed that the lock is only about 35-40% and not the regular 50%

No blade play, knife is brand new.

Doesn't know what this mean and should I be concerned.

Thanks,

Huan
 
nope! just means it's got a long time to wear...I've had 'em from 30-90% and NEVER had a lock fail! Enjoy and don't worry :)
 
Huan,
I would suggest that you take it apart and do a full clean/lube then as CRK suggest do a LIGHT flick. I'm guessing that the knife did not fully seat. If it is still under the 50% and you are really botherd, then contact CS.
 
That shouldn't be a problem. Mine range from ~40% to ~75%. It'll develop more lock-up over time.
 
Your fine, no worries. I always like them in the 50% range, but a little more or less is great. I have seen pics of xm-18's where the lockup is only like 10%, I dont like that. But a sebbie in the 35-40% range, your in perfect shape.
 
I am confused. So the less the lock up is the newer the sebenza is? Is this due to wear and tear?

Thanks in advance.

Every knife is different. CRK states 50-75% lockup is normal I believe. But less is nothing to worry about either. As the knife is used and breaks in over the years, it will wear and the lockup "could" increase. I have heard of knives being 10 years old and being heavily used and lockup has never moved. So pretty much where it is when you get it, is more than likely where its going to be years down the road. An early lockup does not necessarily mean its newer, its just the way it was made. Your dealing with 1000ths of an inch and maybe even smaller amounts while they are machining the lock. The CRK dvd shows this, its amazing.
 
Yeah,all framelocks are a little different.
The location the lock stops at depends on a few things including length of the lock bar,stop pin,blade grind where it hits the stop pin and blade grind where the locks bar hits.Just a couple thousands of an inch on any of these things makes a big difference.Those tolerances are hard to get spot on.CRK does it better than any other.
 
I agree with an earlier poster, take it apart, clean and lube it and put it back together and see how it is then. In my experience, if you dont put it back together exactly right, it will still open and close smoothly but it wont lock up tight like it should and it can also effect how far the lock travels. I noticed that my lock was starting to move way over and was thinking about sending it in, but I took it apart, cleaned it, smoothed up the washers on some really fine sandpaper and lubed it with some tuff glide grease. After I put it back together, its locked up like a new knife, and the lock travel is about half as much. Thats one of the best things about the Sebenza, easy to maintain.
 
My Sebbie gets a lot of use as it is my favorite knife. The lock only travels like 30% and it locks up solid! When I hear that Claack, I never doubt the lockup.
 
Yeah, hbui,

The small classic that I carry every day is about 30% right now. It's been a bit more and a bit less at different times after cleaning. I don't worry about mine after having this one for 4 years and wouldn't suggest you worry about yours either. It sounds just fine to me.
 
Open the blade partway and give it a good flick. Not with all your might, but put a little oomph into it using your wrist. After I clean and reassemble a Sebenza it always locks up early, like 20-30%. After the flick open it goes back to the 50-60% mark and stays there until the next disassemble.
