Have the aluminum, Elmax one. Took it apart, works fine, but the spring rattles when open. What did I mess up and how to correct?
 
I don't have the 0770 but I have two other assisted ZT's that developed the same problem. It's actually pretty common among Zero Tolerance knives and not anything serious.

Basically, the indentation in the handle scales where the torsion bar sits starts out filled with grease. Ultimately that grease dries up or otherwise goes away and the result as that you can hear the bar rattling around. Just a dab of grease (I use white lithium) in that indentation should make the rattle go away.

Good luck!
 
I second the above action. I use white lithium marine grease.
 
Yep. But when VermontEdge says a dab really use only a dab. I have overfilled those cavities with grease under the "more is gooder" law (sp intended) and it backfired and it inhibited performance.

Yeah, all you need is a drop!

Drop it like it's hot!
 
+1 on adding some grease.
Superlube grease is my favorite for torsion bars because it isn't messy and stinky like some other types of grease. Spread a thin layer on the torsion bar and where ever the torsion bar contacts the handle and your all set.
 
Thanks guys. Done and it works great. Who would have thought something so simple. Got this knife, kind of "rough", but the blade was not used hard. Hay this Elmax cuts like crazy, then stays sharp a decent amount of time.
 
Amen Gull! I've been so impressed by my ZT in Elmax. My first experience with the steel but now I'm a believer!
 
Glad I found this. Had the same problem. A little dab of grease on the spring and problem solved!!
 
I found that overtime the grease gets hot and seeps between the seems of the knife and into your pocket also causing a slippery grip. The best solution for this problem I have found is to keep the spring cavity dry and cut off about an inch of heat shrink tubing and put it over the spring, shrink it into place with a lighter and presto! worked great. (Electrical section at the hardware store) acts like a rubber coating sound dampener and its extremely chafe/wear resistant.

No need for fancy lithium grease, high temperature grease is what you need if you want to make it as it was from the factory. You can use the same kind of grease that is used on automotive bearings, it's cheap, readily available, and lasts a good long while.
