First off, I agree with OP.
I do know what is a Okuma, the foundation needed for one and the combined price for tooling were almost the price of my home here in Hawaii - price based on the early '90's. In my past life, as a DOD civilian ToolMaker, I programmed, ran the Okuma, as well as other conventional/CNC machines, manufactured whatever was necessary to "Keep Ships Fit To Fight" at Pearl Harbor Naval Shipyard.
Secondly, I don't buy knife to invest in, nor concern with warranty, simply my toys to play and if areas I can improve upon, to make it my own, well...:
Out of the two pictured, Yojimbo 2, aside at half the price, with its terrific design + excellent S90V blade - is without a doubt, a better knife. One that I don't have to baby, enjoy full speed middle finger flick deployments - day in/day out. Unlike the CRK's soft stop pin bushing, repetitive openings will dent the bushing, eventually affect the lock bar position - which prompted me for an improved bushing, made out of 17-4PH and heat treat for longevity:
CRK does offer the plain Jane titanium handle slab to express my artistic expressions. The soft blade steel, mirror finish took me only 8 hours while the Yojimbo 2's S90V took me a total of close to 40 hours to get the passable mirror.
Other than the factory soft S35 blade which I can not control, CRK is noththing more than a project knife to dress up. One CRK is more than enough for me!
Out of the two, Yojimbo 2 out shines in all aspects for me and did I mentioned it defines - smoothness!?

Another project's beginning stage, lot more work needed to improve and certainly, will transformed:

My standard and expectation are unusual, therefore, I don't go for customs from homegrown/self taught "knifemaker" types.
This already is in the mail from Japan and I don't anticipate any improvement needed from me:

We all have opinions, capabilities and certainly - YMMV.
