Lest we forget - Attention to detail defined in the Sebenza 21

Great explanation on some of the finer details that make CRK's soooo great. Your thread really makes it easier to justify the cost of investing in one of these folders. Thanks for taking the time and all of your attention to detail with this info.
 
Thanks alot for the post. Was worth reading, couple of things I just didn't know about. And I'm carrying a Sebenza as well.
Love it!
 
Good pictures!
The only thing I wish CRK would do is to start using Torx head and get away from Allen head.
The Torx shape can handle torque much better than Allen shape ever could.

Great read, and nice photos as usual Cody. You cook up some great threads brother! My favorite detail by far is the cone inside both the single thumb stud and lanyard pin. This is probably due to my machining knowledge but, how DO they machine those parts like that? I have a few ideas about how it's done but none of them seem CRK-level efficient.

I also see that your inlays have started darkening and taking on some contrasty spots. Somebody has been carrying the Insingo quite often! I've been carrying mine a lot as well. Best wishes to you and your family, my friend!

Trepan tool..It's quite simple. The fact is...this is for aesthetics only. It adds time as this makes this part a two part operation when it could be one. It's something "fun" to do to the opposite side of the thumbstud. :)


Bushings- They are fun..I am more impressed with the thickness than I am the chamfers (45 deg lead-ins) added to them. The controls a whole lot more than you realize such as centering, pivot tightness and feel...The chamfers are somewhat of a necessary evil..Especially with Ti, but they do help later in the assembly process.

As far as I am concerned, the most impressive parts are the assembly hardware such as the male/female threaded parts. They are, for all intents and purposes, they are some of the tightest toleranced parts on the CRK lineup.
Honestly, the whole package is impressive; Titanium demands dead-sharp tooling for a clean finish on anything that is anodized like the thumbstuds. Titanium isn't really a hard material. but it does present it's own challenges..I won't go into details as it's fairly boring manufacturing talk, but is an ever present problem.

Oh ok cool, thanks for the explanation!
 
This might be really amteur to some, but I notice there are two grooves on the top side of your lock bar. I checked my Carbon fiber insingo and it doesn't have them. Is this a inlaid thing?

It's an inlaid thing. I noticed the lines for the first time on one of my micarta Sebenzas.

They only make one style of slab for the inlays. Most of the inlayed slabs (wood, mammoth, leather, CF inlays) end up with a polished surface and those two small grooves help delineate the area that is polished from the bead blast. All slabs start out fully bead-blasted, including the polished slabs, and the lockbar is bent prior to polishing. The non-inlayed slabs don't have these grooves. On the micarta inlayed slabs they are a remnant of something that was not meant to be, and as such serve no purpose, other than to annoy the odd person! :)
 
I'm sure everyone knows this already but it might be worth adding. The blade size compared to the handle. Here is a picture to show what I mean.

Wonderful thread!

A few of my favorite CRK details on my small 21 Insingo:

The rounded edge on the blade tang. Even some very high-end knives leave this part square. It is not only aesthetically pleasing, but also very functional--again, the understated elegance continues to impress:


The open-flow design of the hardware is another aspect that looks beautiful, but also makes cleaning the hardware a touch easier:


The lockbar cutout on the INSIDE of the slab--makes the exterior look sleek and clean, but it also makes for sliding it in and out of the pocket that much more smooth:
 
Well Cody you got me to looking (which you often do) at my CRK. I may have missed it in your pictures but when I look at my Regulars I see this grove in the blade that fits the stop pin. I only have regulars and a Umnumzaan to look at not a MM, 21 or 25 but in your pictures I do not see this grove. Is this only on Regulars or am I missing it in your pictures.

Interesting. The 21s just have the top-half of the curve that wraps over the stop pin, not a true groove like you see on your regulars. This photo below shows that I think. The 25 is different again:

When one talks attention to deatal it isn't always just CRK that come to mind. :p:thumbup:
