sibert 755 mpr blade lock pin

Most likely that sixsided pin has an eccentric shape, and it can be unscrewed & turned when necessary to change the position of the framelock to an early lockup again.
 
If it allows adjustment of the lock up what difference does it make? It probably allows for an easier adjustment with more variation than an 'oblong' pin. Plus most are not oblong but off center. The six side is just a different way to do it and doesn't hurt anything and I certainly don't see why it is lame if it works.
 
The Benchmade 755 MPR is perhaps the best production framelock folder out there today. I have no complaints. I have carried mine the last three days and continually take it out of my pocket to look at it. If the 6-sided stop pin is the only issue then we should all be happy!!! More companies need to make high quality custom collaboration pieces like this.
 
Mine had constant blade play. BM, which has great customer service didn't have a fix for it...

If it had a regular stop pin I would buy one again.

If BM made a Skirmsh sized (4.3" blade) version I might buy one. Then I'd have to wave mod it and tip up the clip.

Wow I didn't know a stop pin had the ability to be lame or cool. :rolleyes:

Have you owned one?

They do have the ability to be lame. The issue is...beyond being difficult to adjust(as you tighten the pin turns). The pin moves when you don't want it to creating blade play.

It doesn't if you do it right.
Remove clip.
Loosen screw which holds the pin in position.
Turn pin to get the side (flat) which gives the lock-up you want.
KEEP IT OPEN and tighten the screw which holds the pin in position.
If you have tightened it correctly (can't understand how one would mess it up:confused:), then the pin does not change position.
Simple really, and a good design which allows one to choose the lock-up they wish.:thumbup:

And yes, I do own one.
 
I totally LOVE my MPR and had no idea about this... I am going to tweak this a bit, I always thought the lock engaged a little too late.
The MPR is the best small frame lock I have every played with, and it is such a TANK.
 
I didn't know that! Can someone explain how that works? Im looking at the pin and cant seem to figure out how tightening/loosening the stop pin makes the lock disengage sooner/later? If someone could explain how to do it/how it works it would be greatly appreciated.
Just got mine 2 days ago. Absolutely amazing piece of work, cant let it out of my hands. Zero blade play on mine.

Each of the flats sits at a different "height", so if you loosen the pin and rotate it to a different flat, it does the same thing as putting in a different size stop pin. Thus, you can adjust the lock-up.:)
 
Okay, I just did exactly what stabman said and the lock-up is at about 40% now and really tight! Thanks Stabman, I never knew about this and just thought the pin was for aesthetics... oh well, what a cool design feature.

Cool!:thumbup:
I think the pin on the Nitrous Stryker I had may have been the same design, but I didn't know that...so I peened the lock-bar to get better lock-up.:o
It worked, but turning the pin would have been so much easier and less likely to damage the knife.
I think Benchmade should include a paper explaining the feature on their knives which have the multi-sided pin, as it would lessen confusion for all of us.:)
