Tool Holder Caddy Attachment for a fly vise stem

This tool holder puts everything I need to tie kebari all in view so I’m not searching for things while tying. Not only are there different size holes to hold different size tools, but the ones for bobbins alternate angling left and right so I can have multiple bobbins with thread at the same time. I only tie a few basic flies, so I am able to leave everything in the holder for next time. I thought it might crowd the work space or get in the way, but it hasn’t so far. I wish I had purchased this when I originally bought my vise.
