Small Sebenza 21 Lockup too far??

After looking at some of my sebbies, yours is furthur than mine are. I always look for something in the 50-60% range. Some of my mnandi are like this though, but since I do not carry my mnandi everyday, I know it will last me my lifetime anyways. All I can say is to email CRK. Enclose a pic in the email and let them know your concerned and a little unhappy with it. CRK will make it right, they have some of the best Customer Service out there.

I'm sorry but isn't the lock bar face titanium? And the hardness for the blade is the one well above? Unless carbide plated?

Thanks

The lock is heat treated which will make the lock face harder than the s30v steel.

Can titanium be heat treated to the hardness of 58? I read somewhere that you cannot heat treat titanium up to that figure. Typically it's going at about 45-48 and that's pushing it.

Thanks.

This lock is fine !! Why do some people insist on making such a big deal out of NOTHING.

Do you think CRK is now just sending poor quality out the door...i'm sure they are getting tired of answering the same stupid questions when the answers are already in black and white. :jerkit:

If it ain't sticking or popping out then don't worry about it...use your knives...if they break, send them in. ;)

In case you guys haven't noticed CRK grinds there blades lock face different than other makers, thats why they work so well and very rarely bind....most guys have a radical grind and the lock bar wedges into it.

If you are so worried about the percentage then you can bend a little of the tension out of the lock bar and it most likely will still have perfect lock up and show you 50,60,70% so you can sleep at night.

Just because 50-60% is in your head doesn't mean that CRK feels the same way.

I have sebenza's that have been 80-90% for years and never had a problem.

I do know this, so you dont have to tell me :rolleyes: It does look to be more than the 50-75% CRK strives for. It does look to be in th 80-85% range. Being a new sebbie owner, the OP was concerned. I like 50-60%, but thats me. I have and do have them in the 75% range and I see no problem. I love Chris Reeve Knives as I have many of them, so in no way is this saying a negative, just expressing what I think. And being a new sebbie owner, I doubt the OP has seen and read ALL the posts here that have answered these questions. Thats why he came here !
 
My Sebbie's lock bar goes all the way baby....I like it when they go all the way!:thumbup:


:D

Better is expecting that the lock will not engage further than mine. I determined it. :D

Dude, it's a 500 dollar knife. 531 if I remember correctly for mine. I'd want it to be perfect and should expect that they are just fine answering the "stupid" questions :jerkit:. I'm willing to bet they answer questions like that all the time and are happy to do so.
I wouldn't recommend bending the lockbar back since it's fitted to the blade and would probably be less safe.
Anyways, lighten up a little eh? Good money was spent and the guys has an honest question with honest concerns.
What if he asks CRK and they say "too far, send it back"?

Well said, when your spending hard earned money, there is no such thing as a stupid question. Call CRK, they will be glad to answer your questions. Anne & Heather are the best.

Ummm, you're not entirely correct, and you've obviously never done it.

If you paid 500 plus for a small , i think you may have over paid by atleast a buck and a half my friend :) :thumbup:

Un like some people, i speak from experiance...your comment is out of ignorance. :D

Let me know when you need another small sebenza 21! I might have a few to sell at that price!! :D

You are correct , there is no such thing as a stupid question.

My point was that this topic is so repetitive that a bold sticky may be in order because folks are obviously missing the FAQ's sticky.
 
IIRC this is your first high end folder and as such I can understand a little anxiety over something like this. I think you have a couple of options. First you can send it in to be adjusted or secondly, you can simply use it and if in the coming years it ever becomes unstable or loose you can send it in to be fixed. The high price tag also means you are paying for excellent customer service and support. Use it without fear.:thumbup:

Very True, I just ordered 3 smalls for $335 so I can sell them for $531......lol. Shop before you drop the $$$

Correct, but titanium can be worked in such a way as to form a layer of very hard (Rc 60+) carbides on and near the surface. To my knowledge, this is how CRK treats their lockbar surfaces. If you take the knife apart, you can see it.

Warren Thomas, a very unique custom knifemaker, makes many knives entirely from titanium, and uses the same (or a similar) technique to form hardened edges on titanium blades.
 
Greetings Cotherion: The following is why I stated what I did previously,regarding the hardness of the LOCK BAR FACE.~~

Ann Reeve, in post # 4 of this thread,(http://www.bladeforums.com/forums/showthread.php?t=127686&highlight=lock+face+hardness
indicates that the mating surface of the lock bar is hardened to well above the level of the blade.

"It is only the face of the lock that moves in behind the blade that is heat treated, not the whole handle. What happens is that when heat is applied to the lock, an oxide forms on the surface. This is very hard (somewhere up at 90 RC) but it is very thin." Anne'

A close examination of the underside of the lock bar where it meets the blade tang should reveal a darker triangular section. That is the hardened contact layer. Which I believe exceeds the hardness of the blade steel by quite a bit. OldDude1

The oxide layer that formes on the surface of Titanuim after being heated is not even close to being the same as a carbide layer. :confused:

Warren Thomas puts a carbide layer on the back side of the blade to form a cutting edge. The Titanium lock bar on a Seb. is heated to form an oxide layer.

This is a Warren T. blade with a carbide edge........

:D Me likee :D

Thanks guys. I had a few customs which the titanium wears too easy and lockbar has travelled noticable in a few months. Admittedly I'm a cronic flicker. I open/close my folders non stop cause it helps with my thinking.

I've stopped using my titanium folders to flick cause of lockbar travel. Now my edc (for cutting and flicking :D) is a SS Poliwog from Spyderco. The ball initially travelled 2 mm and for the past year of everyday non stop flicking open/close (hard force!) it has stopped moving and lockup is perfect still!

My only reservation with the Sebbie initially was lockbar travel cause of my experience with conventional titanium framelock. Now I know it ain't the same and also now I know Titanium can be hardened above 60!!! Thanks guys :thumbup:
