What it is
The Hareline Stonfo Kaiman Vise is a fly-tying vise built around a hardened steel jaw and a lever-actuated quick clamp. It gives you a firm, repeatable hook grip with smooth 360-degree rotation on dual ball bearings, plus adjustable rotary tension so you can spin the hook when you want and stop it when you don’t.
What to tie with it
This vise is for holding hooks while you build flies, and the rotary function helps with clean body wraps, even ribbing, and controlled thread work. The adjustable tying angle, height, and the ability to set the lever up for left- or right-hand tying make it comfortable for long sessions, and the stable grip is useful when you’re stacking tougher materials or spinning deer hair. Tying guides commonly note it’ll handle everything from very small trout hooks up through big saltwater sizes without swapping jaws.
Flies and the fish they're for
On the small end, it’s well suited to trout dries and nymphs in the tiny sizes used for technical rivers and tailwaters, where controlled thread wraps and neat bodies matter. On the big end, it’s comfortable for large saltwater patterns on heavy hooks used for species like tarpon, stripers, and redfish in the flats, bays, and along beaches, where you’re often cinching down bulky materials and want the hook to stay put while you work. The rotary control also makes it a natural fit for any pattern where you want to spin the hook to wrap bodies and ribbing evenly, whether that’s a trout nymph or a bigger baitfish-style fly.
