The Terra Parachute Tool makes it much easier to tie parachute style flies. This tool slides onto the stem of most vises and securely stays put by tightening the thumb screw on the machined aluminum block. Simply clamp a pair of hackle pliers to the parachute post and slide them over the hook on the tool. The Terra Parachute Tool allows you to use both hands to tie the fly and wrap the hackle around the post. Fits 3/8 in. vise stems Qty. per pack: 1
