Cold Steel Black RHINO!!!


Impressed by the Espada and Rajah clips in youtube I decided to purchase a CS Black RHINO. I was mostly impressed by the lock performance in youtube but I wanted a more utilitarian blade and the Black Rhino looked like it fitted the bill.

I have used it for a week and this is a review of the pros and cons of the Black Rajah.

Pros

Clip point blade
Sharp out of the package and I think it's over 4 inches long (we use metric and I have no ruler handy). The blade is quite thick and hollow grind. The tip (a weakness of the voyager and recon 1s in my experience) is also quite thick and could be used for stabbing if the need arises. I had to reprofile the edge to be a thinner (and symmetrical) edge for day to day use.

The blade shape is useful for cutting and the weird little 'rhino-tusk' where the two back edges meet is visually appealing. gives a nice sense of balance since the handle is quite hefty (big). The Aus-8A steel is easy to sharpen and does not need to be sharpened too frequently to maintain the edge. Did I mention the grind is quite high?

Handle
In your hand it feels heavy, in a sort of strong type of heavy. The bolsters are polished nicely and come with some sorta plastic protection sticking on it. The G10 is dovetailed (which is a nice touch) but there were some rough edges in the dovetail (nothing the average joe cannot solve). The pommel is also a solid piece of 7075 aluminum and can be used to hammer-fist in case of emergency.

Gripping until my fingers hurt the handle does not flex (if it did, I didn't feel it). There were no rough edges and the whole handle was smooth. The handle lends itself to a couple of grips like reverse (thumb on pommel is nice), choke hold (ergos is quite good for this) and maximum stretch (holding on back portion where pommel is) is nice due to the curve of the handle.

Unscrewing the G10 shows you the backspacer is secured by 3 torx screws. The pivot screw is also a sturdy design. I like this cause it's not going to fall apart anytime soon even under hard use.

Lock
Very thick stop pin for this folder's size. Initially the lock was kinda stiff and hard but it soon wore out. The thunk of the lock is very pronounced. Like when my Extrema Ratio folder's locks in place. Very reassuring. I am very very sure this lock will take a good beating for a long time and still tick.

Conventional lockbacks transfer forces to the lockbar pivot pin for both cutting and closing directional forces. Conventional lockbacks are quite weak cause there is only a small steel which will shear under high loading even though it may be adequate for day to day use. The Tri-Ad lockback transfers the forces to the fat stop pin. Under super mega heavy loading when the stop pin deforms enough then the lockbar's pivot pin also contributes in the strength. I really like this lock and the thunk of the lock is addictive.

Not to be a nitpicker, but I assume that you're meaning the Cold Steel Black Rhino? You use this knife model once in your review, but "Black Rajah" in a continuing manner.

Thanks for the review; this design caught my eye in their 2008 catalog and the Tri Ad lock and wide, high-ground blade are big selling points!

Cons

Clip Point Blade
The grind is not symmetrical with one side having a steeper grind and the other not. If you can accept/use chisel grinds then your're fine but I'm a bit irritated by this.

Handle

The bolsters are too smooth, slippery even. Scratches way too easy so if you're bothered by scratches on shiny surfaces then take note. The 'guard' is rounded and formed by the bolster so be careful of hand slipping when stabbing.

Handle oxidises/tarnished fairly easy but maybe because I'm in humid Asia. I'm fine by it cause it's a user and not a safe queen. A good wipedown after work then it should be fine.

Lock
As strong as the lock is it is marred by the fact that Cold Steel uses a puny thin spring. Spyderco uses 2.5 to 3mm thick springs but Cold Steel uses a 1.5mm spring. A bit weak but it won't appear so during the first few days of use, why? The spring is in the ideal position when you initially get it. After repeated use (opening/closing) the the spring 'travels to the direction of the lockbar pivot pin. Meaning it gets weaker in time. I ground a notch and bent the spring to make sure mine kept performing like new. Cold Steel did not test out the effect to spring when opening/closing so i'm a bit disappointed.

Thumbstud
Too short on one side but that's just me. I replaced mine to a longer stud and I'm now happy.

Initial opening/closing
Quite stiff but as the contact surface between blade and lock smoothens over repeated use, it'll become more comfortable.

Pocket Clip
One side only and a large pointy (did I mention shiny as well!) pommel sticks out of your pocket. Announcing to the world that you have a sabre in your pocket, Clip is very strong but as I mention, it is on one side only. And did I mention the damn clip is shiny silvery as well!

Torx
I hate little torx screws... Nuff said.

-end of Pros and Cons-

Personal Conclusion
At around 140 to 160 bucks I say gettit. Overall a nice package of sturdy handle, decent blade (steel and profile) and a super lock. Be extremely wary of the lock spring travelling and you'll be fine.

Thanks, I am super embarrassed. Anyone knows how to change thread titles?

-Nevermind, done it-
 
Nice review.

My chief nit with Cold Steel is that they continually overestimate the value of their products. Sure you can pay more realistic prices on Ebay, but what of retailers? The company is built too much on hype, yet its flagship products seem to be consistently good. I just wonder how long the company thinks it can sell $300+ knives using ho-hum blade steels?

Cold Steel continues to stay in strong competition in building knives that no one else seems to want to produce and sell. I love that you can get folding knives with 3-6-inch blades using decent materials and steels (they only get "ho-hum" when they find their way into upper scale knives, which CS is still struggling with). For some reason, they seem unwilling to cross the steel threshold into better, more premium steels. It's almost as though they believe their own hype.

I did buy their monthly special Konjos (2 for $200), and I have no regrets; however, I would never have considered paying their regular $399 each price. The knives were exceedingly well crafted, well balanced and polished, the blades to mirror sheen. But, really, what am I going to use them for? I'm afraid to look at them too often for fear that a scratch will spontaneously appear on those blades. For a hundred each, they're still a bargain. The blades are sharper than hell and like I said, they're gorgeous.

Too bad about CS's spring choice. The Black Sable is a knife I'd like to have and carry, but again, their price is fairly fictional. You can get it cheaper and it, too, seems to be mainly a show knife. The Black Rhino at $260 (even with a Tri-Loc) still only sports an AUS8 blade, and I have a difficult time paying that much for that kind of a blade. Still, I've seen it for sale for $139. There shouldn't be that much of a difference between what you can buy it for and CS's retail price.

If any problems develop, please post. Also, in what way do you think the tips are a problem with the Voyagers and Recons? Have you broken any?

The Black Rhino is a strong, but fairly ugly knife with a ridiculous
price tag.
 
Thanks for the review, a lot of good detail in there. :thumbup:
I am most curious/concerned by your comments regarding the spring. Looking at the Tri-Ad diagram on the CS website, I not sure I understand the problem. Are you saying the spring starts to pull out of it's slot in the rear or does the kink start to straighten out?
 
I looked at one of those a while back and decided against it due to the steel used and the fact it is hollow ground. Otherwise I really like the design.
 
The spring is originally fully in it's slot in the handle. As you use them the spring comes out. This is due to the nature of the Tri-Ad lock (my deduction) where the pivot pin in the lockbar is done intentionally loose. Meaning there is movement on the gaps in the lockbar (to the pivot pin) and it is in the direction of the spring.

Never broken any Voyagers, just that it's very thin tip so I wouldn't stab with it. I would with this knife though cause the blade tip is pretty thick.

Basically yeah, like you said. Spydie lockbacks have a little bump to prevent this but not in the Rhino.
 
I try to give a review after analyzing the knife for it's good and bad points. But more importantly I think that reviews should be structured with the pros and cons as well as end conclusion all separated. I could just write one long essay but that will tire out the readers and hard to understand the points. I split up the point along a few key issues like 'lock', 'handle' and 'blade' so it'll be easier for readers.

Next step is to include pictures and maybe learn how to draw lines in them so I can illustrate my points clearer. Then it'll be better methinks.

Thanks guys for the good words :)
 
Been using it for a while now and I'd have to say I like it a lot. The lock really gives me a secure feeling and I'm liking the cutting ability so far. Mostly I cut cardboard and rope so I don't really test it out too much but I noticed that the bolsters especially around the 'thumb-resting' area and the 'index finger before the guard' is particularly slippery sometimes especially when I sweat and from where I am sweating is a 24/7 issue.

I have ground notches in the areas I mentioned before and now the grip is improved by much. And I noticed that the spring (after bending it slightly to be a little more stiffer lock) stopped moving and stayed in place.

I'm really learning to appreciate a high grind since my endura has a difficult time with cardboard (drag) and the overall build of this folder is very strong in use and as well as in feel. If CS comes out with a version using better steel (154cm, VG-10 (or VG-1) or even better S30V) I'll get it in a heartbeat even if it's 50 bucks more expensive.
 
Great review, thanks!

You know the basic design developed as a skinner,
which the thin, wide, big-bellied blade excels at.
 
I can imagine it would excel at skinning, currently I like it's solid feel when I'm ripping through cardboard (I personally like to destroy cardboard boxes before I recycle them instead of getting my staff to do it, it relieves stress you see) and my tiger stripe notches made it more secure in my grip.

I'll post some pics of the mods in the future tiger dude. By the way, I modded my usual notches to tiger notches cause I got the idea seeing your forum name :)
 
I don't mind AUS8 as it's edge holding ability is quite adequate and it is not as prone to snapping in half as easily when flexing or dropping on a hard surface as some of these so called super steels are.

I am willing to give up some edge holding ability for a stronger blade.

Thanks, I feel better with my Aus-8a blades now. Since they are rough use knives (Rajah 1, American Lawman and my Black Rajah to remember a few) I can accept adequate/medium edge holding for toughness :)

Frankly I never thought of it like this :)
