Hello, everyone,
I recently purchased a BM 810 contego. I really want to love this knife. However, there is significant lateral blade play ( about 1-2mm) that I can feel and see. I've tried adjusting the screw, polishing the washers, liners, and blade tang. As far as I can feel and see it's made no difference. If I tighten the screw to eliminate play, the blade will not even move down when held horizontally and the axis lock is disengaged. I've dealt with minute blade play from Benchmade which I've always been able to fix. I find it rather disappointing to spend 185 American dollars on a knife from Benchmade and receive such poor QC from a company like Benchmade. My initial impression was a flatness issue. But I feel like I'd be able to see such an imperfection. Anyways, any thoughts on what could be causing this?
 
No idea. I had 2 810s and they were both perfect, smooth action, no bladeplay, and overall great. I would send it back to Benchmade.
 
Hey Nick.....welcome!!
Are you able to send it in to Benchmade?? You'll only need to pay shipping one way if it is a warranty issue.
Did you buy it new? From a Benchmade dealer?? If so, the dealer should take it back.

Yes. Send it back if you can. I understand you may not live in the US but bm should still be able to help.
 
yeah i've run into that on some axis locks. there is a sweet spot that can be very hard almost impossible to find. id send it in as well, if you can't find it, or it doesn't exist.

Correct. OP, think about turning the pivot as little as possible until you hit that sweet spot. Then, add some loctite and do it again. Let it sit for a day. This is what I do.
 
^^^ Yup!!! Sometimes the amount of adjustment to find that sweet spot is extremely small!! A little patience and 99% of the time the spot will be found.
