9400
Has anybody taken it apart?
I have difficult to loosen the screws with T6 wrench. Did they Loctite it?

Nope I haven't taken mine apart yet but it doesn't look too difficult.
I'm sure the screws got some Loktite at the factory. The question is "how much"?

It feels very tight. I am afraid of break it off. I think I have to use some heat to do it.
I want the take the spring off.

Arclight, you want to make it a manual?

Ha ha Yes, I like the nice clean blade without the thumb studs. I remember years ago when I first saw a friend holding a knife have these thumb studs. I asked what are these? The first impression is I don't like it and it remains until this day. If I can I would remove them. I did try on 484 but that will leave a hole on the blade so I didn't try others.
I like axis lock without thumb studs but I will take button. :-)
I hope the lock will still hold the blade firmly. Time will tell.
PS, I usually don't like modify knife. I just don't buy it. I bought one last year forgot about it and got another one accidently few days ago.

It's been a while since I've taken apart a push button Benchmade. I believe there is a separate mechanism for the push button & the blade deployment.
Also, I've seen threaded plugs (BK & satin) for an almost flush replacement of thumb stud.
If the 940 & 9400 were both axis, you can do a blade swap of 9400 to 940. I'm not sure how close they are with different opening mechanisms.
There are also several makers of aftermarket 940 blades. Maybe you could have one made without the thumb stud hole? You'd have no markings on the blade, some would see this as a bonus
I have a stripped phillips head screwdriver that i use to break Loctite free. Hold it to the flame for 10 seconds, then the pivot for 5 to 10 seconds. I believe Tim uses a soldering iron.

Tu, please clarify use of that Phillips screwdriver. Do you just hold it against the pivot or do you turn the torx head with it? Thanks!

Yep. Tim uses a soldering iron to loosen Loktite when it seems as though I'll strip the screws in question. 👍🏻

I have disassembled the knife. It was very quick easy process.
Oh, Am I love it without the springs. Yes, yes, yes...
It is absolutely fantastic. beautiful blade and when it close, it locks itself. When it open, it also locks and you can also add manually lock it with the "push lock" mechanism. One hand open and close.
The blade is definitely not changeable with axis lock knife. This is a totally different design.
It have 2 springs inside for the blade open. one on each side.
I also noticed there are no washers. They use the scale to hold the blade. I think this may be because it is auto knife. Another thing is the stop pin is not round and has 5 flat faces and the diameter seems smaller than the regular round pin.
It only hold with one screw. I think this is a way only use the pivot screw to adjust the blade tightness(gap).
Be careful with the spring under the button. It will jump out. It made me crawl on the floor for a while. If you also planning to take it apart.
The screws do have Loctite. I just use a little bit more force and it came loose. (Maybe I was lucky. The safe way is soldering iron.)
I like this EDC and it is legal.

/|\ suggestion: when I upgraded the safety on a shotgun ( plastic to Al) I put a clear plastic ziplock bag over it so if the spring popped out I wouldn’t be crawling on the floor for 20 minutes ( like the guy who made the instructional video).
I missed why you took out the springs, when the 940 been around awhile.😉

I hit it with a propane torch & then rest it on the pivot. I'm more of a brazer/caster than a solderer

On some Benchmades the multi sided stop pin is used as an adjustment so that the blade stops where it needs to & the lock will engage. If this is the case, the sides will all have different size flat spots. If the blade is not seating correctly (worn blade-stop pin connection) you can rotate the stop pin until it seats.
I'm incapable of appreciating a 940, or 9400. The scales are just too narrow, it's like I'm holding the ol ladies pinky. But with 2 springs i imagine it fires with intention, the full size Presidio only had 1. This could factor in to the stop pin design

That is really good to know. One of the face has a dot mark. I think maybe is for identification of which face is the right face for the stop. Luckily I didn't rotate the face. Thanks,

Thanks for the breakdown Arc! Good to know if I ever need to teardown my 9400. Tu is right on when it comes to the stop pin as I've run into that before myself. I just don't remember which model/s it/they was/were. I venture that the dual springs are due to the size of the springs used in the 9400. As Tu mentioned the thinness of the handle of the 940/9400 it's likely they are smaller than what you find in a Presidio. This has me wondering if my Mini Presidio has 1 or 2 springs. I may have to tear it down finally.

And I'll bet you do any framing with a 5# sledge? 😳
Just kidding Tu!

No, that was not a breakdown. Yours are.
PS, both springs are identical, same turns, only one is more expended, I thought they are not the same at first.
I have to practice my finger more to push the button now.
