Flicking My 940?

I just got a brand new 940.... never had one before. Great knife. Anyhow, always been impressed with my friends ability to flick his open and closed. Been at it since I got up this morning - I'm about 95% perfect every time. Closing it is harder.

Question - Is it harmful to do this? I noticed I got some blade wiggle after a while - tightened the screw just a hair and it went away.

Second question - Blue Loctite. I have some - should I do the disassable/reassemble to keep the 'sweet spot' perfect? Are there any tiny parts that will come flying out at me? (I'm mechanically adept I just like to ask first).

Many thanks in advance!

:p
 
Benchmades are not too complicated inside. The omega springs stay put when you take the scales off. I think the only thing you would have lock tight is the pivot screw.
 
Nevermind went for it easy peasy. Prob getting loose so fast because there was visible lube on the pivot screw. Gave it a good cleaning then blue lactate and a hair tighter than I want it... give it 24 hours and final adjust.
 
I don't suggest constantly flicking the knife open and closed, I've just broken my 3rd spring in 5 months doing that. The omega spring don't hold up well if you play with them.
 
I'll take the guy's word for it (3 broken springs) but that's so rare. I nicked one halfway thru w/ a grinder while working on a liner one time-- it never did fail in use.

You spent good $$$ for that knife so if flicking brings you joy-- then knock yourself out! If one breaks they'll fix it, and throw in a new set of washers and a lube job to boot.
 
3 broken springs in 5 months...? It's possible, but I doubt it's common. My first BM 940 of about 6-7 years old had to get it's first spring change around the 4-5 year mark (and I LOVE flicking my knives). All of my other knives never had to be changed even with excessive flicking (but my 940 is my EDC and heavy user). To be honest, I didn't even know it was broken at first (since there are two omega springs). One of them snapped, but it still worked. Nevertheless, all I had to do was send it to Benchmade and get it replaced (took about 1.5 weeks) along with a rejuvenation of the handles, studs, sharpening, etc. Flick that baby open as much as you want. Don't worry about breaking it in such a way. To make you feel better, look at the lock strength on it http://www.youtube.com/watch?v=b3X64SYObO8. Flicking a knife isn't going to do anything.

In terms of getting that "sweet spot" of smooth opening and closing, all you have to do is adjust the pivot screw (the topmost, largest screw near the axis lock... don't need to adjust anything else). You should put a dab of blue loctite on the screw, screw it in to the point of no blade wiggle and smooth opening [note, you can also use plumbers tape on the screw, which IMO works better and less messy].
 
CHARLOOSI Many thanks! That's exactly what I did. My wife thinks I'm a FREAK down here in the basement learning how to one hand my new pocket knife.... but that's what slow days are for, right?
 
At some point you're probably going to peen the stop pin. The Axis is somewhat self-adjusting (depends somewhat from model to model). To me, an old gearhead, wrist flicking is sort of like putting your foot into the accelerator until you hear knocking and then pushing it some more. You're literally hammering on the stop pin, and eventually that will take its toll.

Thanks man! As a lifelong musician I like to think I have the 'rhythm' of the flick and access lock down in a day.... So I'm done practicing and no harm done. Bagels, watch out tomorrow!
 
Only the pivot needs a drop of Loc-Tite on the threads for it to hold. If it needs it at all. Trick: remove the pivot with a T10 Torx driver, clean the threads of any oil, reinsert and adjust to your liking. If it holds true there's nothing else to do. Personally I don't flick my knives, am old fashioned and close either on my pants leg or more often two-handed. Flicking is fun but it places a lot of stress on those springs. Maybe I'm lucky but have never broken a spring.
