Umnumzaan Vs. Large Sebbie

Personally, I prefer a depression to ridges.

I can understand that. Would also argue that the Sebenza's ridges are too far rearward for the purpose you're talking about.

When I close the Sebenza, while my thumb is pushing the lock bar back, I initiate rotation of the blade with my index finger on the ridges. They work well in that regard in the wet or cold.

In terms of choking up on the spine, just having the edges eased is fine for me. The depression starts to look more like a specialized (as opposed to general) tool, which I suppose it might be for some folks.

IMO, it's just a little contrived to have something that I would use maybe 10% of the time, imposing itself so much on the blade's profile. Another thing is that I think the Umnum's profile looks more threatening to the average non knife-carrying person, and the high utility/threat ratio is something I have always loved about the Sebenza.

If possible could you throw up some close up pics of the Umnum's lockup. I'm real interested in the ceramic ball lock face.

Tough request. One, will need to attempt the shots with sunlight and the clouds aren't cooperating. Even with sunlight, the ceramic ball is very small and getting enough light into the tight space(s) will be hard. But I'll try. :D Just not today.





Personally, the Umnumzaan isn't a Sebbie replacement. Bet a dollar to a donut, Chris wasn't attempting to mimic the Sebenza. Innovation is one of the keys to business success and Chris (and team) continue to produce innovative products. The Sebenza is a good example. At one time, nothing but a base model. Then there came to be the Computer Generated Graphic, Unique Graphic, Inlay, the annual Limited Edition and Lisa's Picks (not necessarily in that order). Now the 21.

I don't care much for the CGG and UG. Like them or not. . . . .Chris and team receive :thumbup: :thumbup: for taking the base model and tweaking it to a new level.

The Umnumzaan is another option for the consumer. To me. . . .it's derived from a proven and successful product platform. . . . . .the Sebenza. . . . and tweaked a bit. :D
 
I think the umnum is great, hopefully over the next few years we will get to see some unique versions so that I can buy one as a graduation gift for myself.
 
The Umnum is BAD ASS. That's all I can say at this point! I'm still too jazzed with it to stop playing with it :p I'm surprised at the swedge...it's hair shaving sharp. WOW!
 
gmarthur. . . . . .close up of the lock up. What a pain to get the right light !

Thanks GigOne. Great shots, I appreciate it. Doesn't appear to be a lot of surface area for lock up but I'm sure it's solid. Looks like I'm going to try and handle one of these before I decide on an Umnum or large reg Seb.

Gig, is the ball spherical? It looks like it's taller than the thickness of the lock bar.

Yes, the ball is spherical. The ball isn't taller than the thickness of the lock bar.

It's quite possible that this illusion is due to my photography skills and lighting. :D

My pleasure.

You're correct, there isn't a massive amount of surface to surface contact. I don't believe there has to be, since lockbar tension is the critical aspect.

I'm a firm believer of handling a knife before purchase. Sadly, sometimes this isn't possible. My first Sebbie purchase was without ever having handled one. The monetary expenditure associated with a Sebbie (or any knife). . . .without fondling the product can cause a considerable amount of uneasiness.

*sigh* I relied on the words spoken (OK, typed) here to make the decision to leap. And my Sebenza addiction began. :D So, I hold ALL Sebenzaholics, in this sub-forum, personally responsible for my demise. :D

One thing I've learned over the years. . . . . .you can't go wrong with CRK ! ;) I've owned quite a number and assortment of Sebbies. NEVER a problem. In fact, a large, regular Sebbie was my folder choice for my get-outta-town-fast bag when active duty. . . .and we got-outta-town-fast often. My Sebbie NEVER failed me.
 
So it looks like one difference between the prototype and the production model is that the lockbar balls have been ingeniously reduced from two to one. The single ball on the production model, due to its very smart placement, performs double duty as detent ball and lockup contact.

As with the Sebenza, the Umnumzaan really has to be held and studied to be fully appreciated. Chalk that up to CR's minimalist (in the best sense) design style.

I'll try :p MAN!! The more I play with this thing, the more I like it....was strange at first admittedly...after being so used to the Sebenza, but after using it at work several times today and getting more comfortable with it I've gone from REALLY liking it to being CRAZY about it! Soo incredibly smooth! Smoother than the seb! WOW! CRK hit it out of the park with this knife! It's pretty cool too because it's got the index finger recess (albeit not as deep) like the classic, but has the inward curve for the front two fingers that the regular has at the same time. Another thing I noticed while using it kinda hard today was that where if I was cutting something very forcefully and squeezed the handle the lockbar stayed put becuase of the way it's situated: on a regular seb I would push the lockbar all the way to the wall (which bugged me) when I would squeeze it hard while doing the same kind of cutting (like taking down a 6 ft. tall box or something).

On top of all the great things about this knife and all the thought that went into it's design and manufacture....the thing that makes me smile is just SLAMMIN the SUCKER open! Feels good! I'm always careful to not be too forceful with the sebenza's when opening, but on this thing you can just whip it out as hard as you please because of the rubber rings!

If you're thinking about buying one.....stop it....just go and grab one wherever you can. :thumbup:
 
Well---Now you got me thinking. I'll go take a look at one this week. Thanks, Man. ;)
 
Ok....I need one now. I trust all CRK products to be well thought out and executed. I'll take the plunge. When the wife asks....I'll blame you guys.
