Windsurfing Tensioner Screwdriver.

Designed for windsurfers who want to haul in the sail without hurting their hands and tighten screws with flat and Phillips heads.This winch lets you effortlessly downhaul your sail at the tack. The Phillips and flathead screwdrivers can be used to screw in your fin bolt and footstrap screws.

Lets you haul strong while limiting the risk of hand injury.

The two holes let you insert the line to stop it slipping as you tune the sail, as well as the Phillips-head screwdriver to use as a lever arm when used as a screwdriver.

Enables easy screwing and unscrewing using the 2 cruciform and flat heads at each end.

If the screwdriver you are using does not have enough “grip”, you can use winch as a lever arm. Just slide your screwdriver into one of the holes in the bar and use it as a handle to screw or unscrew.
