Ok, I really want to try this without getting too long-winded which never happens. This is coming from a 21 lover and not necessarily the 25, minus the blade shape and grind. And really only after a few hours with the knife.
Right off the bat, sharpest CRK I've ever seen. They're really stepping up their game here. This edge rivals some of my edges I've put on other CRKs. Beautiful blade too, love the shape compared to a clip point 21. And the jimping which looks like the 25 is nowhere near as aggressive feeling and more like conventional 21 jimping in sharpness.
If you're used to a small 21 handle, and although the nominal difference is minor, it feels noticeably smaller in hand to me. IMO I feel if I took the clip off, I'd have a hard time hanging on to it, particularly when opening. I think the conventional grip (is that saber?) in the left hand is excellent (this is a right hand model and I'm a righty). That got me looking at the grooves more closely, noticing on the lock side of the knife, the index finger groove seems wider and more like the middle finger groove. Well that got me looking at the show side, and I think the tight radius inside the index finger groove that is more functional on the 25 is merely just used as a cutout for access to the stud on the Inkosi. If you ignore the cutout, you'll notice a wide index groove that fits that finger nicely giving a nice right handed grip with 4 fingers. This may be obvious to others, but it took me probably an hour handling the knife to really notice that detail. So maybe that was the design intention all along when we were questioning if the grooves would work. They do. Unfortunately though, the lanyard had to come off in the first few minutes because I did not like how it changed my grip and was overall uncomfortable.
The knife is crazy smooth in a way that feels a little different than a 21. The new huge washers are awesome. I think mine came a touch loose because the blade had the slightest touch of movement I could feel when checking for play. A very slight tightening of the pivot corrected this at the small expense of the original "freeness" of the action though it's not overly tight by any means now. I'll be checking to see if the pivot loosens itself any. I think the lack of a lanyard pin enables a slightly deeper carry than a small 21 also.
I've seen many ask where does this fit in to the lineup. Well, a lot of those same critics will say that the variety of the CRK lineup is lacking. IMO, this knife fits in well for just that...variety. I say that because it's NOT a Sebenza and you've already got the Mnandi near this size. This adds a stout little tank of a folder that is very different than those two. It has its own identity and just a totally different feel than a 21, from the smoothness to the sounds it makes, all in a good way. At this point, I plan to keep it although I won't make any promises just yet because I do love the 21 and am always trying to convince myself to get rid of uncarried knives or ones too similar to others I have, but it does add variety to what I have. But if you like small knives of exceptional quality, and/or you like CRK, and/or you want something that's a little unique or a little different, I recommend giving this one a shot.
Thanks for letting me ramble.
