I looked around a bit on this, and it was suggested I take it apart, clean it, lube accordingly, and reassemble.

Will I F up the warranty it I disassemble it? I can see the knife has the .030 grey Nylatron washers. Do the washers need periodic maintenance or cleaning?

Seriously though, if you have opened it a bunch with no results, first I'd try backing the pivot screw one full turn, then running hot tap water over the pivot. Blow out with compressed air if available, then retighten pivot to preference. If that doesn't show a noticeable improvement, I'd go inside to see if all looks normal with the detent's, particularly the one on the non-lock liner. I once had a brand new Mini A100 with a faulty detent tab - wasn't cut all the way thru.
 
Really, hot water you say? I can do that and I have compressed air. And I do have the pivot fairly snug as I don't like any blade play.

I got the knife off of AZ Custom Knives and it appears NIB, never used. So I surmise that the knife sat somewhere, unused for a number of years, and it wound up in the hands of AZ. It is very very good shape, original factory edge. So your original advice has some merit to it, LOL.
 
Great purchase IMHO, hard to find model. And yes, that is one of the great traits of Emersons (at least the ones sans bearings) - the were designed to survive the rigors of salt water, so tap water is a walk in the park.
 
Nylatron washers are supposed to be self-lubricating, so little/no maintenance should be required. But a dab of lube (I use BreakFree) could help.

What about tough glide? I have that small bottle with the needle tip dispenser on it.
 
Sorry for the dumb question, but, how does the self lubing of nylatron work? Can they dry out on an old knife and need replacing?

Those or my thoughts as well Matt. I wonder if these washers just got dry and brittle with the knife sitting in the closed position for so long. I'm going to run it under hot water as the officer on deck has suggested. If that doesn't resolve the issue, I'm going to take it apart.

Can't hurt to try, and I would definitely loosen the pivot to let the water flood away any grit. I do it with the blade open, holding it with a wash cloth.

Back off the pivot screw a touch, then put a drop of oil in the pivot area. Then carry it and use it. It will continue to smooth out in due time.
 
There are many schools of thought. Other than what's been suggested, you could try to spray some wd40 in the pivot.

What I do is open and close the knife over a period of about 2 days until you can feel it get rough, almost squeaky. Then take it apart, clean everything with breakfree or some other clp, wipe it all down, and put a dab of Chris Reeve grease on the pivot joint before reassembling it. I put a drop of loctite blue when putting it all back together because I also tweak the pivot screw until it's just the way I like it. Not too loose not too tight. Let the loctite dry overnight and good to go. This seems to work with both satin and black coated blades although the the black coated ones tend to get rougher and you can hear a slight squeak or rubbing sound.

I applied some new CRC anti-seize lube and just worked it in and now it is one of my smoothest Emersons yet.
