sgt1372 Did you try taking the scales off, packing some heavier grease (vaseline works in a pinch but may leak out if it gets too hot and liquifies), not oil, in the cutout that holds the bar/spring, replacing the bar in grease and then reassembling? That usually stops the rattling and the assist still works fine.
It usually rattles because the grease from the factory has dried up or leaked out...
I had the same issue in a standard G-10 0566. I run it manual now, and its a solid little flipper.Same here; whether assisted by a torsion bar or spring.
The only problem I have w/certain assisted knives is that the assistance spring is loose and rattles. This generally isn't a serious enough problem to bother me but it was so bad in my ZT 0566CF that I removed it and thereby converted the knife to a manual. Still works fine but obviously requires a little more effort to open.
I'll never buy a speedsafe knife ever again. Just bad. They make them cause it's popular among non knife people. Flippers are much better. Tho I do prefer thumbstuds overall, preferably if it can be flicked open and middle finger flicked open.
The blur I have is the only one that has a decent on close for speed safe. My zt 0770cf I hate because of speedsafe.
Closing knives with speedsafe is the killer for me mostly.... But those torsion bars break alot too.
Torsion bar is the way to go because of its much simpler design. I have a SOG Twitch II and it is a nightmare in terms of complexity compared to my Kershaw Dividend. The draw back is that you can't close it one handed, but you can certainly open it without the "intimidating" thwack that comes with some assisted openers.I have never had a torsion bar break and have been carrying Kershaw and then ZT's for years...I have had some that developed a rattle but a little grease fixes that right up.
Good deal, some of them run as manuals better than others...No didn't know or try that.
There was no grease in the 0566 which is probably why it rattled. Actually like it better w/o the spring in it; better matches the 0560 an 0562 which are themselves manuals.
