The Whiting Hackle Gauge gives you an all new method of measuring hackle for dry fly tying. Taking into account the gape measurements of today's most popular dry fly hooks, the Whiting Hackle Gauge provides the most accurate and comprehensive measurement tool on the market today.
I really like the way the hole is oblong so that the guage sits at an angle on the vise pedestal. That makes it easy to use.
Durable with clear markings..
