Sebenza lockup problems?

Livefreeordie92 said:
I've had 3 sebenzas, all of which I could get a very small ammount of up and down lock flex/lock rock out of. It's annoying as hell. Especially for a knife that's supposed to be perfect. Anyone else have this problem, or is this just normal? Idk. It almost makes me want to stop buying them.

Man why does it always have to be you!! The rest of us get the good ones and you get the rejects. I agree with you...stop buy, that will teach CRK's.
 
Unless you have a vid confirming your claim I just don't believe it. I can believe one out of 3 that could have developed bladeplay but all 3? Just my experience with multiple sebenzas ranging from early production to now is complete opposite. One thing that out of many that CRK gets right is solid lock up. Hell you can take the pivot pin out and it still locks up solid.
 
It seems that many people sit around trying to find miniscule "issues" with their knives rather than actually using them.

Since they don't actually use their knives, the supposed "issues" should not be of any concern to them.:)
 
I love that "click" when any of Seb's are opened. I love the solid position the blades have with zero movement vertically, horizontally, laterally, back and forthally. I love that "ting" when the stop pin hits the blade when the knife is closed. It's all very satisfying. Sort of like when you feel a sneeze coming on... You huff, you puff, and the. SNEEZE! Yeah, that's right, I compared a Seb to a sneeze.

Did someone say lock rock or blade play? What the foul is that?
 
Own 4 sebs (small/ large/ inlays/ damascus) and two Zaans. Years range from '08-'12. No play on any...period.
 
3 smalls, 1 large, 2 umnumzaan's and 1 mnandi have passed through these hands in the past year. NONE of which had any issue what so ever.

If I pressed down with all my might I'm sure I could get the blade to "click" like you are describing, however that is not the point.
 
IF any of my CRK's had any lock up issues I would freak, key word here is IF... and IF it was to happen a complete repair is all but a phonecall and a post office trip away. If you are unhappy, send it back and have them take a look. That is a better solution than asking the forum which wont solve your problem since knives of this caliber rarely have this problem.

But judging from your posts, I do also recommend you get some worry beads/stress balls or something. It's not impossible to imagine someone torquing it hard all day long everyday until a knife develops play. You can break anything just for the sake of breaking it, even expensive knives.
 
I can force tiny movement in one of my sebbies the Zaan and the 25, not really an issue in any way tho. ive never heard of "lockrock" on a CRK period. and yes you can force movement on pretty much every folding knife, its build with multiple parts that moves.
and if you opening and closing you knife as a worry bead made it develop play, you worry about WAY to much man, becouse you have Sebenzas thats 10+ years old that holds up, just think how many times those have been opened in all those years
 
In every single CRK I have ever handled, small sebenzas, large sebenzas, and umnumzaans, I could feel movement when the knives were fully opened. Most of these were new and it is many more than I can count. It isn't the blade flexing, it is the lockbar flexing. It is an element of the design. If someone says they can't feel movement, more than likely they aren't trying hard enough.
 
You can design a framelock to have absolutely zero flex vertically. The trade off is having a very short life span on the lockbar because of how fast it wears and you end up with terrible vertical play ie Strider. You can go the opposite direction and have maximum life span but that would lead to a sloppy lockbar that slips very easily and causing significant flex/lock rock. I feel that Sebenzas and Umnumzaans are in the sweet spot between the two.

But that is to be expected. Of course if you muscle it, you can get the Ti to give and flex, a bit. That is not the same thing as blade play.

I don't recommend yanking and pulling on the blade hard enough to cause lockbar flexing, by the way. That can't be good for the knife.

IMO, if someone says they can feel movement, more than likey they are trying too hard.

You are probably right about the flex being an element of the design, but I would never do that just to see if it would flex.

This poster started another thread on his XM-18 having lock-up problems. OP: you may be doing something to your knives that you shouldn't.

I think you have serious problems in discerning meaning within statements as your reply to his post on the aforementioned xm thread suggested he send it in. Do you read statements/questions in their entirety before responding? I understood his xm post to be a question as to whether or not he should look into buying one based on other people's experiences in terms of lockup. Decipher meaning before you assume the guy just outright abuses his knives.

Very well said.
 
All of the six or seven I've had through my hands have been rock solid. I think your mind is playing tricks on you maybe:D
