Hello!

Yesterday i received my BM 710 - it's great! BUT: The compression lock seems to be to 'strong' or rigid: I only can open the folder (via gravity opening) with maximum effort. Is there a possibility to loosen it up??

Thank you in advance,

Zedd
 
If you hold the axis button back the blade will fall open provided the pivot screw isn't to tight.
 
Hello!

Thank you for your answer!
But i'm searching for a method to use the gravity opening without holding the button (it's a problem of this 'lock', not of the blade), because in 'reality' (under maximum stress) you don't have the fine motor skill to hold this button. There i'd like to rely on 'bigger movements'!

It is not possible to have the blade drop out of the handle by gravity. It uses the Axis Lock to keep it from opening up in your pocket via a notch on the bottom of the blade similiar to the notch on the top of the blade. You need to manually move the lockbar back in order to release the blade. There is no other way around it. You cannot open this knife by gravity alone. It's not a problem of the lock.....it's a safety feature of the lock. It's to prevent accidental opening. If quick deployment is what you need then you need to get an automatic.
 
You can always flick it with a little bit of wrist, but like K.V. says, it will never drop out of the handle by gravity alone. I don't think you'd really want that though. An open knife in the pocket is not fun.
 
give a nudge with you thumb and then flick... If that's not fast enough you need to buy an automatic.
 
The trick to fast deployment under stress is practice,practice,practice.This will develope muscle memory and you will be able to quickly open your 710 without even thinking, under any situation.

I presume you mean that you can open your BM Axis faster than "you" can open an auto.
If so, your auto is in need of a serious adjustment. What kind of an auto do you own?

That might be true. But if you are after the fastest from the pocket, then you are in Emerson Commander territory.
From the pocket, I agree. Many folders are faster than an auto.
 
With some practice most folders can be deployed from the pocket faster than an auto.

The key is practice. If you won't put the time in to learn the best method for you with an ordinary folder [ wrist flick, inertial, pop, etc ] then an auto may be faster for some.

Autos are not really a legal option for many to begin with.

Hello!

I woudn'd rely on "Auto-Folders" - i have the feeling, that they are too 'unsecure' under fire....

As to the 'axis-lock-opening-problem': I practise a LOT on these openings and with other knifes (BM Griptilian etc.) it works fine. Therefore i asked, if there is a possibility to 'loosen up' the axis lock!?

I don't think you can really "loosen up" the axis. You can loosen up the pivot but then you will get some blade play.

Although I am not a big fan of the Emerson production knife quality, I do own a good number of their knives. I must say, with practice, there is no folder as fast, out of the pocket, as a waved Emerson. The knife simpy is open as soon as you pull it out. Cannot be faster. And with practice, it is quite secure. The one thing I do not like about the wave, is that the knife always opens when you pull it, quickly, out of your pocket. Sometimes I don't want it to open!!
 
...yes, the wave is a great opening device! But i don't like the Emerson-Folders. For me they are not worth that much money!

I stick to my BM, MOD an CRKT :rolleyes:

What do you mean by gravity opening, I'm a little confused. I can flick my axis blades with no problem. It seems easier if you switch the clip to the other side and draw into reverse grip. A very easy snap of the wrist opens the knife.

^^^Oh yeah, this may be your problem-the axis bar moves back as you open the knife. If your thumb or index finger is on the bar as you grip and try to flick it, the knife won't open.
 
Warning!! Warranty voiding advise ahead!!! If you have a problem please dont sue me!!!

To loosen the Axis lock this is what you have to do.

Use a dremel or a diamond file to flatten and round the edge off the spot where the axis bar rests on when the blade is locked or closed. DO NOT flatten the face until the bottom where the axis bar rests or the blade will open too easily. You also need to polish the areas grinded off so the axis bar will travel smoothly. What you need to get rid of is the bit where the axis bar goes out all the way before going back in again. The position if held with the handle at 6 o'clock and the blade at 5 o'clock.

Be careful and take off a bit at a time and test that the blade does not open too easily. Glad to be of help.
 
Have you tried loosening the pivot a bit? Might want to give it a shot before you start removing metal.
