PEAK Midge Jaws are available for both the PEAK Rotary Vise (MDG-1) and the PEAK non-Rotary Vise (MDG-NR). These jaws undergo the same hardening and tempering process as our highly acclaimed standard jaw. Our midge jaws are specifically profiled to allow more access to tie on smaller hooks. Not recommended for extended use with hook wires larger than a #16 dry fly hook. Black oxide finish reduces glare in the immediate area of your fly.
