Is it normal for an Omega spring to be sticking out of the liner like this? Knife is a 940-1

Thanks. Do your 940s have unevenly finished shoulders before the blade tip? This gives an impression of poor centering.

Also, will Benchmade shear the excess screw threads that protrude out the liners?

it is common for the grinds to be a little off on the end of the blade just before it slopes down for the tip. That has to be a tricky grind to execute on that knife. I believe they may be able to send you shorter screws if you call or email and ask for a set. I don't mind the longer ones though.
 
But the omega springs are supposed to stick out. That is what keeps the tension. if they weren't stuck into the liners they would have no tension and thus not work at all.

I sent my 940-1 back to Benchmade for these same reasons, asked the blade be replaced with matching grind on both side, centered, no recurve in the flat part of the blade and no protruding screws inside the scale,... For the price they charge for this knife these to me aren't nip picking but should have been done before they are introduced to the market, I feel they cut a few too many corners on this one. We will see how they did when the knife comes back to me.
 
Hey Beans.....please let us know how they take care of you??
Thanks
Joe

I started a thread awhile back on the official Benchmade forum about the protruding screws, to try and determine if this was a defect or intentional. I can't answer the quoted question, and I'm a total layman when it comes to knife manufacturing, but Jason (design engineer) of Benchmade offered this explanation, which was helpful:

"The 940-1 is designed so that there is ALWAYS maximum engagement from the liner screws into the cartridge liner, because it is a relatively thin liner.

In a production environment, the final dimensions of various components and features (such as handle thickness, counterbore depths, screw lengths, chamfers, etc.) vary accordingly with the capability of the manufacturing processes used to create those features.

So essentially, we bias the design at nominal conditions so that the screws stick a little bit through the liners, so that if screws are short, counterbores are shallow and/or chamfers are oversized, the screw threads will bite throughout the entire thickness of the liner. Not only does this give the knife more strength and stability and more firmly locate the liner in the handle, but it makes it so that you are less likely to accidentally strip a screw, further compromising the integrity of the assembly.

However, this also means that in the opposite condition, the screws may stick a little further through the liners than intended.

Long story short, sometimes the screws stick through a bit and sometimes they're essentially flush to the liners, but they will always have max engagement with the threads. However, they will never interfere with the blade. There is plenty of clearance.

Functionality is always the focus, because at the end of the day, these knives are tools and must be able to be treated as such.

Hope that provides some clarity.

Jason"
 
Ok so I got my 940-1 back from Benchmade, as promised here are the run down and pictures:

First let me list out the to do list that I noted to Benchmade on the warranty form:
1. Replace blade due to uneven grind from one side to the other and recurve in the middle of blade that should've been flat.

2. Make sure the blade is centered and swedges match

3. Have black thumb studs and stone washed split arrow clip or black if not available.

4. To address the protruding screws inside the scales.

And here are the pics, you guys see it for yourself


Packing was well done and I included the paperwork showing the work order they listed at the bottom of the page


New blade is Straight!! No recurve in the middle





Scale screws are still protruding... I still don't buy the whole story that the screws were intentionally designed that way, the regular 940 doesn't have this issue and many other models don't have this issue yet this premium model of the iconic 940 has... My opinion is they just don't want to spend the money and order a slightly shorter screws for 1 model knife that won't be shared by other models, understandable in a manufacturing stand point but again this is a upgraded premium model.


And here they slapped on a regular chrome split arrow because they don't have stone washed one. Way to ruin the esthetic..... They did put on the black thumb studs for me thou

Remember I wanted matching swedges on both sides? And... This puts evenness into a whole new meaning.... Again this is THE premium model which they claimed to be made with best material and craftsmanship.


This BRAND NEW blade doesn't cut/slice very well.

Why? They sent it off with a pretty evenly distributed burr still on the blade, it's not even a wire edge, I was unable to strop it out and it needs a sharpening to correct that problem which will cost $30-40 to have Josh (razor edge) do it right. Again, Premium model from a top knife manufacture.... I don't mean to bash but if any of you think this is acceptable should go see a shrink.

I am totally NOT impressed; I can understand these type of flaws coming off production line and was a quality control oversight. But coming from warranty department where their only job is to make things right and this is the end result?

I will be ditching this one in my local classified because I'm not a gold member here and frankly I don't want to pass this one off to someone on here anyways.
 
Ugh. That sucks Beans.
Suggestion.....send it back bro. No reason for you to settle for that if you aren't happy. You'll probably wind up with more cash in your pocket when selling it also......just in case the buyer knows what he's looking at.
If it were me, I would call first and go through all your issues before you send it in.

Wiredbeans, I’m sorry to hear. I sent mine back yesterday for sharpening as it struggled to cut ruled paper =(, cleaning/re-oiling, installation of a plain deep carry clip, and for Benchmade to address the poor centering/uneven shoulder grind and the protruding scale screws… I’m less hopeful now. I can live with these deficiencies but I figure, why the heck would I not try and get these ‘wrinkles’ worked out?

Thanks for the input Joe and to OP, I'm terribly sorry that it looks like I'm high jacking this thread.

I don't have the confidence at the moment and instead of me spending another $20 (it's now $40) additional cost into this knife to ship to Benchmade and have no guarantee that they will address the issues. I'm in Canada, this knife cost me $335 after tax and it's now $355 with shipping cost which is just about $300 USD. I have own this thing for 1 and a half month now and have zero time of enjoyment out of it so far... Locally I think I should be able to sell it for $250 CAD or about $180 USD. I will take my $100 loss and go on with my life and stay away from Benchmade until they are able to deliver what they advertised.

Maybe I'm just that 1 out of a million who is really unlucky to receive a poor quality product off the production line and 1 out of 10 million that the warranty department overlooked a few too many things?
 
The only manufacturer that I've seen consistently put sharp edges on knives is Emerson. Some are better than others, but I've always had to reprofile my ZT, Kershaw, Benchmade and Spyderco knives out of the box.

This is a surprise to me and I would think most here. I can't speak for zero tolerance because I've not owned one, but my Spydercos and benchmades have always been extremely sharp out of the box, with the exception of my value line Spydercos, which were still good but not as good as the higher end knives. Maybe you have an extremely ridiculously high expectation of sharp, but being able to cleanly shave and easily slice thru phone book paper is in my book very sharp.

I use the Wicked Edge, so I'm definitely holding the companies to a higher standard now. :)
 
That sloping transition on the spine seems to be present on all the 94X. I can't believe that's a hard problem for them to fix. It's just sloppy.
