Couldn't help but notice that if I turn the screw when my Military is closed, I can adjust the "centerness" of the blade.
However, it tightens up, instead of tightening OR loosing, if I continue turning either clock- or anti-clockwise (maybe because of the blade being in extreme position).

Strange. :confused: Wonder how it works? But whatever it is, it's a damn good idea.

Edit: Forgot to mention that I manage to find a Military (older, CPM 440V, engravings on blade) at my friendly dealer today and snap it up right away. It'll be replacing my SOG as EDC (read in Good, Bad and Ugly). If I "tune" the Military just right, I can flick it even faster and smoother than my BM axis or SOG arc-lock. Man, I love this knife!!!
 
It's called an excentric pivot pin. I'm not sure how it works, other than it does work. Someone here can give you the details. I beleive Spyderco has a patent on this...

It's really cool, because Spyderco has adressed two major problems of liner locks.
1. Their reliability after wear (eccentric pivot pin)
2. Their strength (NESTED LINER LOCK)

Hi Allen, The eccentric solved some mfg problems, but it also created a few. It was a nice "improvement" at the time. We now have new people in engineering & machining (since the Millie was originally engineered). We found that we could make some refinements that solved the mfg problems and didn't create any new ones.

I might also add that we are still experimenting with other possible refinements. One of the complaints that I hear often from vendors is that I'm always changing and improving our products. To my way of thinking, time always creates new solutions and it is our obligation to our customer to make those changes.

On the new (S30V) Militarys, if they no longer have the eccentric pivot, would it be considered okay if the ELU adjusted the pivot screw him/herself and not have to send it in, *if* the pivot ever happened to loosen over time? (I have not yet had such a problem, but just in case).

Hi Jim. adjustment shouldn't be a problem. The problem with ELUs taking the knives apart is that a large percentage of them cannot put them back together or put them together incorrectly. Then they send the parts to us in a plastic bag and want us to put the knife back together (usually missing parts), and they expect us to do this at no charge.

By voiding the guarantee if ELUs take it apart, it means that we can charge for the work done to put it back together and for chasing the missing parts.

Thanks, Sal!
I personally never trust myself to disassemble my knives, even those knives that are designed to be disassembled/reassembled, but the pivot adjustment had always been a concern for me.

Now, couple a pivot screw that can be ELU adjusted, with the easier-to maintain S30V in the new Militarys, IMO the Military is the best liner-locking folder, and one of the all-time best folders, period.
