Here is a little break down I did for another forum.
Here is some pics of my CRK Umnumzaan. I bought a take down kit and tried it out tonight. First pic is it all taken apart:
Really it is only 10 pieces completely broken down. Top of the picture is the lock bar side of the scale. Below that is the backspacer (stand off) and the two bronze washers. Then it is the blade. Followed by the pivot and the stand off female and male screws. Then the front scale. That is it, just too simple.
Now here is the source of the Umnumzaans power. In the lock bar itself there lays a ceramic ball detent. CRK uses ceramic because SS balls will eventually flatten out. Ceramic is much harder and will not flatten out. Not that this is any different then a Sebenza. What is different is the place ment of this ceramic ball. It is placed close to the end of the lock bar, so close that it is actually in two places of the lock bar. It sits on the side and on the end so as to touch the side of the blade and sit in the blade detent. It is so close to the end that the titanium never touches the blade steel. It also is made to slide on the end of the blade on the tang. This is normally where the titanium part contacts the blade tang causing lock up. Here are some more bad pics:
All this means is that ceramic is always touching the blade steel and never the titanium lock bar. This will extend the life of the knife lock up.
IMHO This is one of the most thought out but most simple designs on the market. Sheer genious.
