CRK tolerances

Just a side remark: the blue ano of the thumb stud looks pretty worn off. Did you buy a used Sebenza? If yes, how can you be sure that this issue is caused by CRK? If no, please ignore my comment.
 
If you bought it new, just return/exchange it. If you bought it used, why?
 
Compassion to you stef142.

I had an offcentered blade parking on a Small 21 Carbon Fiber (slab), and like you wanted to fix it myself. I ordered a titanium slab from CRK(fortunately they don't require a return to the factory for that). It worked out pretty well, it's much better. I'm just out for the carbon fiber, and no eight weeks wait.

I hope these reports of discontent don't continue.
 
BladwHQ shipped to you? I had difficulty getting them to ship here (although they were very gracious).
 
Photo #2 looks more like an assembly issue.... if not, back it goes!
 
stef142, have you tried a different tightening sequence to see if it would help?
There are several ways to take down a Sebenza, some jus remove the blade and leave the body intact. Some take it all the way down.
Maybe you could loosen everything and try to snug the stop pin screw first, the back spacer, then the pivot. Or the back spacer first, pivot then stop pin. You might be able to see when the blade starts going off center as you snug each screw.
Don't know for sure if this will help, but it's a start.
 
I think you may be looking at the lanyard pin and not the spacer. Spacer looks tight to me. But, I have been wrong before...
 
A pinched washer will give an off center blade like in the one pic you posted. I know there is no way in hell that left the CRK shop that way.

CRK will not send washers out as each are hand fit to each individual knife. 1/1000" will make a difference. This is the same with lockup%. Watch the BHQ video or the Exquiste Blade video. It Will give you a better understanding of what goes into each knife.

By sanding the washers, you did more harm than good. Now the tolerances will not be as tight and issues can result. Looks like there was simply a pinched washer and you jumped the gun. Washers can be easily pinched, even by a veteran...........I just sent a small 21 in for a spa as the previous owner badly pinched the washer. I cleaned it up and it functioned fine, but I know it wasn't right, so off it went along with another that I have been meaning to send in for 10 years now.

"There is no way it left CRK that way."

You may be right about this knife, but you're wrong in general. I used to work at a store in Birmingham al that is one of the largest CRK dealers in America. I have seen *literally* hundreds of CRKs.

I have seen numerous sebenzas come straight from Idaho with WAY off center blades. They'd be packed up, and sent right back. If a dealer doesn't inspect each one, they'd get sold to the public in that condition.

I know of 3 examples that I held personally that were so off center that they scrubbed the Ti scale. So yeah, they most certainly CAN come from Idaho in that shape.

What is meant by a pinched washer?


When you disassemble the knife and take it apart for cleaning and in doing so, you use your index finger and thumb to hold the washer for cleaning, it's pinching the washer :D
Or, upon assembly, a washer gets out of place unknowingly and gets pinched between the bushing/blade and deforms the washer.

Thanks AJack. So the thin washers get a slight bend or kink in them from being pinched. Makes sense

I had one arrive with an off-centered blade that rubbed the non-lock slab, but I sent it back to the dealer immediately. I'm not sure how the OP's knife would have been more or less fine when new but way off now, unless the washer had been pinched?

Yeah, that's what I was thinking. I've never seen a Sebenza that far off center without an assembly problem. But we'll have to assume the OP knew how to reassemble the knife.
