The QuicKey and SkullKey are key-shaped tools that fit right into a keyring like any other key, but include a flathead screwdriver (also fits #2 phillips head screws), a scoring point / box cutter, a serrated saw edge (great for cutting string or tags), a file, and the always-needed bottle opener. These durable stainless steel tools won't cause problems at airport security, either. The SkullKey features the same tools as the QuicKey, but with a stylish skull design on the head of the tool. The QuicKey measures 2.5 x 1.0 x 0.2 inches (64.2 x 25.2 x 5.1 mm) and weighs 0.69 oz (19.56 g), while the SkullKey is just a fraction thicker and heavier at 2.5 x 1.0 x 0.2 (64.2 x 25.2 x 5.6 mm) and 0.73 oz (20.70 g). Both versions come in a stainless (silver) finish.
