Rattle in Kershaw Sweet

[GWashington1732]

I have been noticing a rattling in my Kershaw Sweet that has been gradually getting louder. It still works fine, it just rattles like crazy, only when it's open though. I don't remember if it's always done it but does anyone know why it's doing it? I know it's the torsion bar but I couldn't see anything wrong with it when I took it apart.

I just checked my Blackout just out of curiosity, it does it too and I've hardly ever used it, is this just something they normally do?

Hey GW. I had the same problem with my zt 302. This is normal for speed safe knives.I took off the g-10 handle and coated the torsion bar with a little bit of thick grease. Don't need much. Rattle free for over a year now ,with no ill effects!! Hope this helps.One more thing,be sure knife is open before you take it apart!!

Yep, this is what you do to solve the problem. :thumbup:

The rattle is not a problem though, but I do agree, it can get annoying at times.

Open your blade into the locked position before you take it apart, if not, you'll have a heck of a surprise when the pieces go airborn.

Yeah, I got that the first time, it was like a Jack in the box. What kind of grease should I use?

I think any kind of thick grease would work. Something thick enough to stay in place. Like I said before though,you don't need much.

What about chainsaw bar oil? That's all I have laying around.

No. Oil is too runny. Automotive grease will work. Stop by a Juffy Lube with a little paper cup and ask for a squirt. You need about as much as the size of a pencil eraser.

I use white lithium grease personally and it works like a charm.

Thats exactly what I used! ............. GW ,as SPXTrader said ,oil will just make a mess. You will not be using the grease for it's intended purpose . You will be using it to give the torsion bar something to stick to . The grease will stick the bar to the inside of the handle. Won't rattle then.

I asked ZT/Kershaw exactly what grease they used on their torsion bar. They use either of these two products:

I've had good luck with some standard axle bearing grease that I use on my dirt bike. It was handy and worked great:thumbup:

Grease worked, the rattle is gone now.
