whats this piece called?

[clockworkfish]

hey ive seen this on a few knives its between the blade and the pivot pin and seems to hold the blade in place, what is it called?

It looks like a washer that serves as a bolster of sorts.

 

[clockworkfish]

seems thicker than a washer though, and it doesn't move when the knife pivots

What you got there is a "doohickey".

It's just a decorative pivot head AFAIK.

+1 :thumbup:

Also a small chance it could be a widget or a thing-a-ma-jig.

I thought it was a whatchamacallit?

I agree with Vege Taco though. Looks like it is just part of the pivot intended to look cool.
