I watched a vid a few days ago by a BF member who has made quite a few vids I've watched. I didn't get the link tho.

If you have a CRK with lockup % of at least 75-80% you Might want to try this. I'm Not Recommeding it, just telling you what I saw on a vid.


Loosen all the male screws about .75 turn, hold the knife in you hand with your thumb on the bottom of the back scale pushing up and

your fore finger, of the same hand, pushing down on the top corner of the front scale. While still holding pressure with your thumb and fore finger,

tighten the bottom screw, the pivot screw, and then the standoff screw.

I changed the lockup % on my regular from 85% to 50% and the lockup on my 25 from 90% to 70%.

I'm Not Responsible for anything you do to your knife. I used this method on my CRKs and it changed the lockup % a bit for me.

Again, I'm not Recommeding you trying this method on your CRK, it worked for me tho.

The lockup percent on mine has changed a lot by just taking it apart and spinning the stop pin.
 
spinning the stop pin may help if its not perfectly centered but everything else is temporary until you fully seat the blade by giving it a delicate but firm initial flick.

You got it. Chances are, though, that the stop pin sleeve is pretty well perfectly round.

The whole point of the post assembly flick is to seat all the parts back to a solid location. Any slight bind you get from this lockup "trick" will be reversed with a solid flick. The Sebenza is not designed to be adjusted like other knives.
 
I've tried rotating stop pins on several different Sebenzas with absolutely no change in lockup at all.
 
I would see no reason to manipulate it yourself.

Every CRK I have ever had, lockup has been perfect. If it isn't, you should probably send it back to them. They know what's best for their knives.
 
Indeed, I have had people show me this "trick" and when I see them a week later the knife is back to the way it was and they are full of ummm's and eh's. :p

This trick only makes any sense to me personally, using my understanding of basic geometry, if you are somehow managing to re- tighten your knife with one or more of the posts or the pivot pushed out of square at a minute angle; essentially pushing the stop pin forward or the blade pivot back. You are setting your knife off -square. My guess is that in so doing you will cause even more wear on the components as the reseat themselves all jammed up and off centre, and will need to press harder and harder with each "trick" rebuild until one scale is noticeably forward (or proud) of the other scale. Why not just dig the 80% lock and relax? I dunno, what's the big deal?
 
It simply relies on the small amount of clearance necessary for the parts of the knife to be fitted in working order. It actually does nothing in reality and all parts seat back to the original and intended position in fairly short order. This bee people have in their bonnet about lock up percentage is just silly, if it ain't broken don't fix it.....
 
Video is done by JDavis. The point of the trick is to move the lockbar closer to the blade so it engages sooner, but I think at the end of the day it just goes back to normal, the tolerances are just too tight to mess with. If your lock up is too late, CRK will service it for free. If your lock up is later than you'd like but within spec...learn to love it or just get a different knife. (:
 
I apppricate the comments guys. I had doubts about this trick myself also.y I haven't used the knives enough to see an change in the lockup %, but all

the comments have been very negative. I expect the lockup to return to their original positions.
