Hareline Hackle, Hook, & Bead Gauge is a multi-purpose measuring tool for the tying desk, offered in Brown, Olive, and Purple. It takes the guesswork out of material selection by letting tiers measure hackle length, check hook sizes, and gauge beads before they ever touch the vise.
Use it when selecting hackle for dry flies, confirming hook sizes for a pattern, or matching beads to hooks for nymphs. It is the kind of tool you reach for constantly once it lives on your desk.
A small tool that makes every fly more consistent. Measure twice, tie once.
