The Wolff Indiana, LLC Apex Vise® is an in-line rotary fly tying vise equipped with replaceable jaws, c-clamp, pedestal base, and material clip. The Apex Vise® is crafted from 440-C and 303 stainless steels with 0-1 tool steel jaws. The jaws fitted on your new vise are designed to accommodate hook sizes from 7/0 to 32. An extended finger pin with ball end for easy wrapping can be located in any of four pre-drilled positions. Combining the stainless steel construction, knurled friction knob and cam action lock produces a smooth, solid, and precise feel. The c-clamp assembly ships fitted to your Apex Vise® held in place by a black thumb screw on the back of the c-clamp. The c-clamp attaches to a flat surface up to 1-3/4" thick by adjusting the brass knob. The Pedestal base ships conveniently packaged under your Apex Vise®. The stem holder screws into the base to provide a secure, steady platform for all of your creations.
