I have the opportunity to purchase a lnib lg CF sebenza 21(knife art version) that I have personally seen on two different occasions. The B. Date is 2014 and the knife has been very very lightly carried. He is asking $400.00 and I defenitly like the knife. My question is w/ the CF slab. Will it age gracefully like the ti slabs on my reg lg 21? I will only use the knife for general purpose light EDC applications. How long has CRK been producing knives that utilize CF slabes? Any insight and or analysis regarding this mode/subject would be greatly appreciated.

If you want it get it. Whether it ages as well is moot, as CRK warranty it's going to back up your purchase.
 
They age very gracefully. I'm coming up on a year of daily carrying mine and I haven't exactly taken it easy on the knife so far. The CF will take a LOT of dings and abrasion to look bad. More often than not, I can't even notice the wear on my CF scale.
 
If you want a 21 that will show character marks with age/use get 1 with all ti. CF isn't going to show marks/dings like the original.
 
What about where the pivot, washer and opening/closing parts make contact w/ the CF slab? I'm no engineer, but I would think that Carbon Fiber would be somewhat susceptible to the frictional forces that occur when opening/closing the knife. Please advise.

My view point on that, as someone who also doesn't have an engineering background, is that if CRK sees it fit for use and there have been no complaints thus far, it is a non-issue to me personally. Like I said, a year later, and my CF model feels no different than day one.

Regards,
 
my large CF 21 is my favorite knife. I don't take it easy on it and it still looks great. I do carry it in the leather slip sheath though. I've thought about the issue of contact of the components to CF too, but well done CF can be strong as metal. I have two mountain bikes and prefer letting my fat friends ride the CF one because its actually stronger than the metal one.

There is nothing working against the CF slab. As far as I know, the blade rotates against the washer, so there's no wear on the frame. All the CF slab does is provide rigidity, holding the screws and everything in place at 90 degree angles from the frames. There are folders that don't even have a slab on both sides, look at the dogtag knife from Spyderco for an example.

I have an engineering background, and I'll eventually be picking up one of the CF slab 25s. I love knives like the CF Sebenzas, Strider SMF/SNG/PT, or BM 755 that use only G10 or CF or whatever for the non-lock side - they prove that full metal liners are mostly unnecessary :D
 
Thanks to MatthewSB, Zeta33, thegamettt and everyone else who responded to my questions on this specific thread topic. I can't wait to put this blade into the CRK portion of my edc rotation.

Good choice!

Also....If you're worried about the washer digging into the CF, just make sure that no Loctite, or anything similar, gets in the pivot that would fuse the washer to the blade :D

You'll post pictures when you pick up the knife, right?
