Skeleton Key Pinhole Bow Metal Sign

About the Pinhole Bow design

A single small hole pierces the round bow, and it sits well off center, pushed toward the outer rim instead of the middle. Where the bow meets the shank, a slim collar steps out on both sides before the long bar runs flat to a rounded tip. Near that tip the bit drops as a squat block with a square notch bitten from its underside, leaving two short legs standing apart.
