Along with the usual assortment of fly tying tools at my desk, I have this ...
little red wire.
It's a piece of brassie size ultra wire that I use to be sure the eye of the hook is clear of material and head cement before I put the fly in the fly box. Since I started using it, I very seldom am frustrated while on the water trying to tie a fly onto the tippet.
So what do you use ??
