Abstract: A hammer holder with means of support to a worker's belt includes a ring in a generally horizontal orientation to hold a hammer handle. A movable gate bridges a gap in the ring to permit passage of the hammer handle between two opposed ends of the ring opposite the support. The gate is supported to a fixed end of the gap to rotate inwardly to permit the passage of the handle into the enclosure. A spring between the fixed end and the movable gate member urges the gate outward to closed position defined by stop means. Alternatively, the gate may be two gate members supported by the ring at opposite ends of the bridge gap, each with its own spring means urging the gate outwardly and opposed stops on each supporting ring end and supported gate member to hold each gate in closed gate position against spring pressure.
