DOT Common Sense/Lift-the-DOT® Fastener Tool comes with two interchangeable dies—machined out of 4140 hardened steel—to prepare fabric for use with both Common Sense and Lift-the-DOT fasteners. Created by a marine fabricator, the tool was designed to save time and money by allowing fabricators to properly place fasteners and make small repairs without having to remove the fabric from its application. Manufactured of billet aluminum with an ergonomic design, it can be disassembled for pin and blade sharpening. Comes with a two-year manufacturer warranty.
