Here's something I found while on a quest for some spacers to go between the T handle and claw on one of my vintage sets. I found these craft "beads" (or more correctly "bead spacers") on ebay. They are 8mm x 8mm with a 5-6 mm hole through the center. They are made of stainless steel and they are relatively cheap. They look nice too and stainless kind of works with either nickel or chrome plating.

Anyway, just a heads up if you have a need for something like this. They worked great for my application and look "correct". Much nicer than a stack of washers or a plain steel or nylon spacer sleeve.
