A Question about Eccentric Pivot Pin

Does this refer to "adjustable" pivot pin? And is it a torx screw? Also, when (the catalog) says an eccentric pivot pin for adjustment of the liner lock and tang ramp, how is that done? Is this similar to the adjustable pivot screws on the Benchmade knives? (I don't know how a BM liner lock could be adjusted via the pivot screw.)

Okay, that's way more than one question.

They're probably silly, but I'm strongly considering buying my first G-10 handled higher-end Spydie and would like to know this before buying one. In particular, I'm looking at the Military (finally), or maybe the Starmate. Or should I wait for these to come out in compression lock?

Bit complex this, but after stripping my Military, I noticed that the pivot pin? Had an irregular shape to it kinda oval in profile. Wait, no I mean the watsit called? The pin bar thingy...awe god I forget what it is called

. The pin that stops the blade from continuing to open beyong fully open, the top bar? Well I seem to remember it can be rotated to keep the triangle tight.

By triangle I mean lock,stop and pivot.

I am quite sure the pivot has room for adjustment. Sorry if I have confused the issue here.

I believe The General is referring to the stop pin. Thats all I have to add to this, sorry...

According to Sal Glesser in prior posts, the pivot pin, which is inside the scales, is an eccentric shape, i.e. not exactly round but sort of egg-shaped. This is the pin around which the blade pivots, and it adjusts where the ramp at the back end of the blade falls relative to the top of the liner part that springs out to lock the blade open. The purpose of the eccentric pivot is to allow adjustment to allow for the best possible contact between the liner lock and the ramp, about 1/4 to 1/3 of the way across from the left, or beginning, side on both my StarMate and my Military. Sal very strongly recommends that the adjustment of this eccentric pivot be left to the factory service department.

The torx screw on the outside of the scales at the pivot adjusts the tension on the pivot and, therefor, the tightness of the blade. It can be adjusted with a No. 15 torx screwdriver. I would suggest some care in this as, for if you loosen the pivot too much, you may then become legally subject to carrying a "Gravity Blade" if it can be flipped open easily without the use of a thumb in the hole to assist the blade. Mine was too tight for my arthritic hands when I got it, so I did loosen it a bit, but not much. I also lubricated the pivot. Since the knives are "tip down carry" you ned not fear them openning in your pocket, at least.

As to waiting for the Compression Lock, I have a Gunting which is my daily in town carry because it has a Washington, DC legal blade length of 3". But I also have both ther StarMate and the Military, and, truth be told, the StarMate is my all-time favorite carry knife. I consider it fully the equal of the Chris Reeve Sebenza, less the obsessive non-functional detail for 1/3 the price, and with better steel in the blade. INCOMING! I prefer the StarMate for its shape and feel, but the Military is damned near as nice, just shaped differently and for somewhat different uses. If I had it to do over, I would not wait for the Compression Lock, as I am not certain if it will be offered on the StarMate or the full-sized Military, or, if so, when. And I have never had one of Spyderco's adjustable linerlocks fail or release unintentionally on me.

THanks for the time for the replies, guys!

That clears up some questions I had...never would have thought the screw was oval shaped.

I'm going back and forth on whether I want a Starmate or Military. But I'm leaning heavily toward the Starmate. I like the blade shape and the overall looks of it. The only reservation I've had on either of these knives is the steel, due to its reputation for being difficult to resharpen. But I suppose if I don't let it actually become dull, and maintain the edge on my Sharpmaker (esp. when the diamond rods for it come out if the job is too difficult for the ceramic rods) it'll be fine.

Ah yes the stop pin!

Wait a second...good stuff, but let me add a few things. The pivot pin is round, but is slightly off centered in relation to its position in the pivot pin hole in the scale. The pivot pin has small teeth (like a gear) that sits into teeth on the scale. By rotating the pivot pin, you change its position in relation to the lock bar face, and stop pin (the triangle alluded to earlier). This way, by adjusting the pivot pin, you can compensate for lock wear.

I am sorry, I misunderstood the drawings that I had seen of the pivot pin. Dano, thank you, your description makes good sense.

Do go for the StarMate, you'll never regret it. You can always get a military later, if you really want one. I did it the other way around, and I don't use the Military nearly as much as I do my StarMate.

The Starmate is a "chubby chopper" (sic)

These are some really good verbal explanations of the eccentric. Most impressive.

Thine understanding be vast and deep.

Does the Military have an eccentric pivot?
The one I got has the diamond engraving so it's not the very latest version. I was reading the 2001 dealer's catalog and it only mentioned eccentric pivot pins, I believe, for the Viele, Lum tanto, and Starmate, though on external inspection, the Military and Starmate's pivot screws look exactly the same.
