The performance of our vises lies in the unique design of our head and jaws which consistently hold the hook in place better than any of the competitive vises on the market, and allows for immediate change in hook sizes with absolutely no adjustments. This saves time and frustration and the tier can meet the demands of the next fishing outing in one tying session. Tie a dozen midges, nymphs, dry flies and streamers all in one sitting with no hassle to adjust the jaws. Simply sit down and tie what you need to fish. ?Each Regal Medallion Series Vise rotates 360 degrees and pivots 220 degrees up and down.?
