Hareline Bead Sizer and Measuring Ruler

Description:

What it is

Harelines Bead Sizer and Measuring Ruler is a stainless steel bench tool for checking bead size and measuring tying materials. Its built to be durable and gives precision measuring with dual-scale markings and bead-sizing holes.

What to tie with it

Use it to match bead diameter to hook size when youre building beadhead nymphs and streamers, and to keep your proportions consistent from fly to fly. Its also handy for measuring material length for tails, winging, and shank-length references when youre stacking, trimming, and setting body and wing lengths.

Flies and the fish they're for

This tool shows up any time youre tying beadhead patterns where the bead adds weight, balance, and a more insectlike profile, which is a big part of modern nymph and small streamer tying. Dialing in bead size helps when youre tying flies for trout in rivers and tailwaters where sink rate and depth control matter, and its just as useful for beadheaded flies aimed at panfish and smallmouth in creeks and ponds where you may change bead size based on depth and current. Even though specific patterns arent listed here, the practical use is the same across most beadhead nymphs: pick a bead that seats cleanly and tracks right for the water youre fishing.
