Titanium Pocket Bit
Weighing in at just over four grams — roughly half the weight of a normal house key — the Titanium Pocket Bit makes a versatile addition to your keyring that will be virtually unnoticeable in your pocket. The titanium alloy bit offers a #2 Phillips head on one side and a 6mm flat head on the other, and works with the titanium keyring to let you drive or loosen screws by turning it like a key.
