Good day.

My first CRK is the Large Sebenza 21 with the Ladder Damascus.
Awsome knive and absolutly love it.

But i'm a beginner in the knive world and maybe i did some mistakes (by accident) and i have some questions and i'm sorry if they will sound stupid/wierd.
So, here it goes.


I want another CRK to my collection and love that i have the original Sebenza design and functional art with the Damascus blade.

Another reason is because i think the Damascus is kind of soft (?).
I think i abused it in cutting some mild frozen meat (?) and some portions from the top of the blade don't cut anymore (only those small portions- and the light reflects on them)
I mean this is the hardest scenario until now - 1 month of owning it.
And only regular EDC stuff - paper, plastic, carboard boxes etc
The rest of the blade is hair poping as it came from the factory.
What do you think?
Stupid of me trying to cut that ?


Oscilating between the Umnumzaam and the 25.
Umnu is in stock right now but 25 only on e-bay/luck on forums.
I know the tehnicall specs on them, i'm looking on first hand informations and feedback.


As you know there are a lot of opinions on the internet/formus etc and it's hard to get some right informations.


0. I love the pivot bushings on the Sebenza and minimal maintanace and want to get another one with the S35VN blade but the 'rumors' say that the S35VN is 'soft' on the 21s and the edge retention is not that good.
True?
And now in my mind, after my unlucky Damascus screwup, i think i need a tougher/harder blade.

So, these is what is in my head:

1. On the Umnuzamm, can i install a second back spacer in the lynard hole, (in my mind) to increase the strenght of the knive ? Will the blade touch it?
(I know it's overkill but is it possible?)

2. When the o-rings wear off, any damage to the knive if i use it without them for a while?

3. Is the Sebenza 25 better than the Umnu regarding overal strenght/build?

4. True that the 25 has maybe a higher RC rating + the new blade grind cuts better than 21 / Umnumand and has better edge retention ?

5. Hard to get the knives (Umnu/25) centered when putting them back together?

6. Purple locktite good if the screws may come loose? (25/Umnu) - This brand good?

http://www.amazon.com/gp/product/B0002KKTT0/ref=ox_sc_sfl_title_3?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

7. Any recommandations on aftermarket grease if the original one is not available and it's an 'emergency' ? Is this one good ?

http://www.amazon.com/gp/product/B002L5UL92/ref=ox_sc_sfl_title_4?ie=UTF8&psc=1&smid=ATVPDKIKX0DER

8. What system do you recommand for a begginer in sharpening the CRKs?
Spyderco sharpmaker good choice/results?
Because i need to put my edge back on my Damascus and for future purchases.
Do i also need the ultra fine rods as well ?

http://www.amazon.com/Spyderco-Ultra-Fine-Triangle-Stone/dp/B0019JTNDQ/ref=pd_sim_sg_1

9.Or should i hunt a Sebenza with the BG-42 ?
So with this i will have what i think i want - the Sebenza design and a tougher/harder blade?
But very hard to find?
An estimate on the sh price?


Sorry for so many questions.
Any imput is of great help.
Thank you.

I would DEFINITELY go with the 25. I've had both, sold both, and then got another 25. And I'll be honest - I don't think there's a better knife out there. The 25 is IT.
Now, I don't wanna sound rude, but many of these questions you asked, you'll find tons of info on if you use the search option. Probably way more than you'll see in this thread, due to so many questions.
All CRK's should center perfectly when closing, or upon reassembly. If it doesn't, it's probably something you did, and not the knife.
Personally I use blue loctite, but purple is a good equivalent. There will be many others who say not to, so, it's up to you. I DO.
As far as heat treat, I don't think you'll be disappointed. There's a reason why these knives are the best on the planet. And the best part is, if you don't like it, you can easily sell it, and make most or all your $ back. Except for the Umnum.. Those things do not sell well. Trust me on that one!
Just get yourself a 25...and you can thank me later :-)

I like my 25 more than my Umnumzaan too! Obviously!! Haha!
 
I'm sure if you sent the knife back to CRK they could sharpen it back to factory specs, in the meant time try not to use your pocket knife to cut up frozen meat!! :) I have both 25 and Umnumzaan, both are great knives in there own fashion. As far as resale value on the Umnumzaan I think if you purchase a new knife for $425.00 take care of it and don't abuse it you could easily recoup 85-95% of your original cost. JMHO

Perfect.
Thanks guys.
So yeah my fault.
I tried to search all of these but i couldn't find very exact answers but maybe i din't look hard enough.
I don't expect all on the same time answered but little by little - that's why i put everything in the same basket.

But in the mean time the ballance is with the 25.
I put the Umnu because it is on stock right now.
Maybe i'll get both :)

So again any info little by little is of huge help.
 
It's in stock because it isn't wanted. The 25 isn't in stock because it IS wanted. Buy one here. If you don't like it, you'll be able to sell it for what you paid for it. Easy.

not sure I agree with this 100% I would lean more towards the new factor of the 25. Personally I prefer Zaan over the 25. I do agree though that you wont have any problem selling either should you not like it.

Once you become proficient with you sharpening you'll gain confidence in the sebenza's ability, even the damascas.
 
I carry and use Devon Thomas Damascus daily and find it very good. The harder Rc on the supersteels would probably benefit you more in heavy cutting. That said, you probably just "rolled" or "flattened" part of the edge that either contacted the frozen material or what you were cutting on when the blade slammed through the food. A light reverse(back) strop on leather or a piece of ceramic should bring it back to scary sharp.

Knice knife by the way!

True?

That rumor basically tracks back to one disgruntled YouTube video. If you were to spend a few days (I am not suggesting that you actually do that) searching and reading at various knife forums, you'd find very, very few people who agree with that based on actual use.

1. On the Umnuzamm, can i install a second back spacer in the lynard hole, (in my mind) to increase the strenght of the knive ? Will the blade touch it?
(I know it's overkill but is it possible?)

I don't have an Umnumzaan with me right this moment, so this is a guess, but I guess that the blade would strike the backspacer. In any case, and this is not a guess, it's total overkill.

2. When the o-rings wear off, any damage to the knive if i use it without them for a while?

No damage, but replacements (that seem to be more durable than the ones CRK uses) are readily available from Amazon. I'll try to find a link.


5. Hard to get the knives (Umnu/25) centered when putting them back together?

Not in my experience. YMMV. ;)

6. Purple locktite good if the screws may come loose? (25/Umnu) - This brand good?

That is precisely what CRK ships with these knives and it is the perfect product.


9.Or should i hunt a Sebenza with the BG-42 ?
So with this i will have what i think i want - the Sebenza design and a tougher/harder blade?

I love my S30V and S35VN CRK folders, but I also have a pair of BG-42 Sebenzas and they are my favorite blades, so if you have the interest in seeking those out I think you'd be very impressed. Warning, though: if you let these blades get dull you will spend quite a bit of time getting a good sharp edge back on them. ;)

Thank you.

Thanks guys for the info.
Now that i've searched more and plus what you provided i see things differently.

Thanks blackend ! :)

@ JNewell

0 - Yes now after more seaching almost nothing from practical evidences and here on the specific forum.
1 - Now i remember , it was a tanto blade of the Umnu and maybe that's why no blade touching; it was on youtube ; anyway i was just curious.
2 / 5 / 6 - Good.
9 - Nice with the BG-42. If i found one i will like one just to satisfy my voice in the head for the need of a stronger metal :)

Thanks again.
I just ordered the Spyderco Sharpmaker and will start from there to learn to sharpend and see how it performs.

If i see i need another blade i will have a lot of options; the 25 maybe be more available, the umnu is now and the 21 and maybe a bg42 for my collection and why not a s30v to have all the flavours.

Have a good one.
 
Great answers jnewell.
The only one I sort of disagree with is the umnumzaan second back spacer question.
I believe that if you have a good custom maker and are willing to spend a little money to have one made, or are handy with a mill that one will fit, take the Brad Southard backspacer as an example since it uses the lanyard hole as a support against twisting between the handles.
His backspacers fit the regular harpoon shaped blade but not the Tanto or I'd have one for mine to try it out. I spoke to Brad at Blade 2012 and he told me then that if I sent him my knife he'd make one but I've since read that he's no longer making them so they're getting pricey if you can find one.
If anybody makes a high quality stand off that fits or a back spacer count me in for one.

I don't think that you'll be disappointed with S30V or S35VN but everybody is different.
