1st Benchmade DISASTER

trying to unlock by pulling only one side seemed awkward and uncomfortable. In fact, I think I only tried the one-sided axis bar pull once or twice before abandoning it.
This ^^^^^
I don't disbelieve the one side release causes spring fatigue but I'm trying to imagine EXACTLY why this causes the springs to fail. All I can think is the spring gets spiraled and maybe the spring is square stock rather than round wire and can't take the spiraling (torsional loading). I've never seen one. Is it made from square stock ?
Some body fill me in on why one side releasing breaks springs.

I've never never had a failed lock or spring either, on any brand from any knife. Theres more to qc than just not outright breaking down
I wrongly assumed when you mentioned AXIS locks being a crapshoot you were referring to lock problems, particularly broken springs as there was considerable discussion regarding that not far back in the thread.

I'm with you on there being way more to good QC than not breaking down. I've got lots more knives than my current two dozen BMs and have a good sense of quality of design and manufacture. I just haven't run into the problems that others have described with their Benchmade knives. Any small centering or blade play issues have been easily resolved with adjustment and break-in.

When you pull back on just one side of the lock, the AXIS bar moves unevenly. The opposite side retracts maybe a bit more than half way. This would put greater strain on one spring than the other and I suppose this could lead to failure.

I almost always draw back evenly on both sides of the lock as retracting on one side often will not fully release the blade.

I think the question would best be answered by a Benchmade representative. It was originally made known to me by a Benchmade design engineer, in a post composed on the Benchmade Forum, directly and succinctly addressing the issue. It was thereafter reinforced and reiterated to me personally, by a Benchmade engineer, in connection with the replacement of my last broken Omega Spring. For, it is with great shame, I admit being a former single sided disengagement douche. Lol.

However, once implementing the proper procedure and protocol conveyed to me by the BM engineer approximately five (5) years ago, the plague has been lifted from the land and not a single Omega Spring has in any way failed me.

In my former post contained in this thread, I alluded in a cursory manner to the engineer's explanation of why the classic "Pincer Manuever" should be the sole means of disengaging an Axis Lock. In lieu of attempting to relay his thorough but reasonably concise explanation, in my own painfully boring, verbose and pedantic words, far better suited as an insomnia cure for those unlucky enough to wade through the muck, I would prefer to defer to Benchmade's official reasoning. Thus, if my short and somewhat conclusory answer set forth in my former post is as insufficient as I would imagine it to be, I suggest the question be raised in BF's Benchmade subforum.

Edit: ChazzyP ChazzyP summed it up rather nicely, though the official BM explanation was more intricate and detailed.

palonej palonej : It sounds like we shared a similar experience involving a polite engineer secretly wondering whether our IQ exceeded our shoe size, due to our former disengagement errors, though yours was at least limited to one instance. Lol.

Nightmare story and not typical. I am not a huge Benchmade guy but have had several in clouding a 940 and they have all been perfect. Sometimes you run into a str8ng of bad luck and I hope is the case.
 
When it rains it pours.
My past Benchmade knives have all been very impressive, I would even say perfect.
I guess they either really hit it or miss it..
 
I find the customer support and service pretty amazing that you experienced. I would hate to have the experience you had. I own one Benchmade knife. It is the US brand that I resisted buying for the longest time and finally I just decided I wanted to try one.

I have experienced few mechanical and assembly type knife problems with any brand of knife, but I don't spend $200 on many folding knives either. I'm probably not as picky as many and usually just park the knife and not worry about it. With your 940... I would be torn as the cost would push me toward seeking a remedy. I have no solutions for you or special insight into Benchmade. There has to be a remedy as there are far too many satisfied customers that own that knife.
 
Disengagement errors??? I like it, but it can also be said a bit more crassly.....ya big dummy!! Pull back on BOTH posts!!
I remember being told when pulling back on one post only, the lock bar comes back crookedly. Thus putting that spring in a cocked position while pulling more weight than it should.
The 908-1501 is the only BM I closed like that, by pulling back on the post on the presentation side only, and it's the only one that ever broke a spring.
The broken spring was the one on the side I was pulling back.
Sounds correct and it works.

Well looks like they won't be fixing the knife since they won't take responsibility for their manufacturing defect.... they just sent the knife back.

That was beautiful. I enjoyed that.

Sorry. Not good. :(
If you like the knife and money rains down on you in buckets you might get one of the pros here to grind the tang flat and maybe they can then shim it to center it and get rid of play etc.

Otherwise there is always the fancy paper weight gambit.
 
Without knowing the complete history of this knife, I guess the only alternative I see, if you want to keep the knife, is to get a new blade installed.
I think that blade is about $30.
 
Send it to someone that knows what they are doing. Benchmade obviously don't.
 
I just received a $625 knife NIB from dealer and there are a number of issues with it.
- 0.5" edge wonkiness like you wouldn't believe
- The last groove in the backspacer's jimping looks like an 8 year-old was given a chisel and had at it
- Blue anodizing wore off clip and spine from 5 minute car ride to dad's house to show him knife
- Several scratches in the damascus near the tip

I could send it back and eat $62.50 for the restocking fee, so I'd rather just keep it and use this horr...or.

Welcome to the knife world.

Mind sharing which Benchmade it is?
 
Mind sharing which Benchmade it is?
It's a Millit that's been classified as a, "Custom." Not even a mid-tech or anything. Sorry if my post insinuated my knife was a BM product.

I wanted my knife to remain a bit ambiguous (but I can post closeup pics if it's not considered thread jacking) since my goal isn't to launch a complaint about the maker OR the dealer. Rather, I was trying to find relevance with the OP in that I've been displeased with knife purchases (well above the $180 mark) numerous times with little recourse.

As far as BM goes, I have four and am very pleased with three of them.

Gosh one would think Bm would have jumped at the chance to sell him a new blade and win a happy customer.
? . . . ??? . . . o_O . . . ? ? ? ?
 
Got my 940 in the mail today from the forum. LNIB. Nearly perfect centering, blade drops free, smooth action. Guess I got lucky.

Will be my new EDC
