This V-Dart V thread tool retracts for compact storage and has a sharp hook at the end that snags your webbing, cord, or rope to guide it thru the V thread. To use, grasp the V-dart like a ball point pen. Bend the top with your thumb to expose the eye and push it out. Grab the tip (careful, it's sharp!) with gloved fingers or hook it and pull firmly to extend fully and wedge in place. To retract, squeeze the wedge and push the hook back into it's sheath. Only 5-5/8" long and weight 10 grams, but extends to reach your longest 22 centimeter screw! Racks easily on a carabiner when not in use. Also effective for clearing ice from inside the screw, retrieving gear from cracks & crevices, and removing hair from the shower drain.
