Ive been looking at some Elishewitz knives on KnifeArt and it says that they have a Bolster Lock. Can someone please explain what this is and how it works.

PS does anyone own an Elishewitz knife, and if so what are they like ?

Thanks

JD
 
Is this good enough? -AR

Hey Jackyl, you wouldn't happen to have a pic of his other locks as a comparison, would you?

Thanks,

Mark

I have a pic of the liner lock on my Elishewitz...but we all know what those look like, and the integral lock is the only other one he uses I believe. That's just like the Sebenza and the BM Pinnacle. No pic of that one. -AR

Ok...ok...here's a pic of the liner lock. -AR

As I understand it, the bolster lock is a variation of the integral frame lock like what is used on the Chris Reeve knives, CRKT's S-2, and the 710 (?) by Benchmade. The difference is that the scales will cover some of the frame lock, essentially making the exposed titanium toward the blade bolsters. Since the exposed part of the lock is also a bolster, they call it a bolster lock! Does that make sense? The idea behind the bolster lock is cosmetic, but also gives all the advantages of a frame lock, with the added benefit that the scale on the lock side prevents the lock from being pushed too far away from midline and weakening or overstressing the "spring" (which is also the lock itself, of course), during closing. Hope this makes sense.

Similar to, but not the same (or as good) as an integral lock.

Yeah I'm crazy, but what do you want me to do about it
 
So, um, what keeps your finger from getting pinched in there when the lock is depressed and that gap between bolster and scale disappears?

Nothing Drew. The gap also makes an excellent place for dirt and debris to collect, and a breeding ground for micro organisms.

Chiro75,

The idea behind the bolster lock is cosmetic, but also gives all the advantages of a frame lock, with the added benefit that the scale on the lock side prevents the lock from being pushed too far away from midline and weakening or overstressing the "spring" (which is also the lock itself, of course), during closing.

I've never heard of anybody over stressing an Integral lock. Just shows how hard it is to improve upon perfection.

Am I seeing things, or is there a notch on the tang to stop the lock from going further right. ALso, there appears to be a part of the lock that overextends beyond the tang on the left side which would also preclude movement to the right. If so, more machining involved.

I can see that many of you aren't big fans of the bolster lock...I think it's a huge improvment over the liner lock, and that it was a great idea. I don't see the gap being a problem. -AR

Chiro75 you gave an excellent definition of the Bolster-Lock. I hope it answered the question.
I would like to address some of the other comments:
The gap is not more of a problem than in a regular liner-lock and at least with the Bolster-Lock it is exposed and you can blow out lint and dirt that could get in there.
Your fingers are not getting pinched by the Bolster-Lock just just like they are not by a regular liner-lock.
Also, a frame lock CAN be overstressed if you are not carefull when disengaging the lock.
Finally, there is nothing on the lock to prevent it from going further under the blade. It just looks like it in the picture.

The main advantage of the Bolster-Lock is that it gives you a frame lock with a handle material and not just a plain piece of titanium.
Thank you,

Allen Elishewitz
 
Thanks for the picture Jackyl. I have a Phantom on order and just wanted to jack up my anticipation!!

I haven't handled a bolster lock yet, so I've mostly been silent. But as a lock sceptic, I'm still favorably impressed with the bolster lock from the pics. I noticed the gap also, but figured I'd handle one first to see if it's really a problem. Doesn't anyone out there have a bolster lock, who can tell us definitively if there's any problems with it?

I’ve been carrying one of Allen’s Mars folders with the bolster lock for about four months and I’m very pleased with it. The lock up is extremely solid and I’ve had absolutely no problems with junk accumulating in the space between the locking bar and the scales. As Allen mentioned, it’s actually easier to keep this area debris-free on a bolster lock than it would be on a conventional liner lock.

These aren't my pictures TANGUS, the Bolster lock came from Elishewitz's website, and the liner lock is a scan of my knife that Ray Satterfield took. Thanks again Ray. -AR

Chiro75,

The Benchmade knife you speak of is the Pinnacle 750. It has an integral lock. The 710, which I have in my pocket right now, is the Axis-Lock, which I like very much.
