Hello guys.
I own this awesome blade and i really like it!
But i have one question when the blade is opened and i shake the knife i can hear the sound that assist spring is rattling. Is it ok? I mean is that a feature of speedsafe mecanism or there should not be any rattling when the knife is opened?
 
Many of them rattle, open her up and put some Vaseline or light weight grease around the spring (don't over do it).


Will do the trick!!
 
Kershaw/Zero Tolerance put grease in the torsion bar cavity. This keeps the rattling down. When the grease is cleaned after a disassembly, the rattle will show up. It should be fine but, if it bothers you, just take the g10 scale off and put some grease under the torsion bar.
 
It doesnt bother me, so spring rattling is somehow okay for this model.
I will apply to spring some grease, think that will save it from rust and corrosion
Thank you sirs!
 
When the knife is open. The spring isn't under any tension. You can tell because you can close it part way before you feel the spring engage. That's why the spring can rattle, it's just sitting there.
 
Yes, torsion bar rattle in ZT/Kershaws is normal when open (reason stated above). As noted, you can add some thick grease to minimize it, or just leave it as it. It won't hurt anything. I just let mine rattle, since I know what causes it. Some of Cold Steel's Tri-Ad knives can rattle too, due to the small stop pin down inside the handle that keeps the blade from closing too far and contacting the lock spring. As long as I know the rattle is a harmless byproduct of the design, I don't sweat it. I only start worrying when a knife rattles that shouldn't. :D
