Disclosed is a wallet comprising two shell halves which are associated by a rigid spine to open and close the wallet, and containing a bunch of keys, anchored to the wallet. The wallet is biased to the open position by a pre tensioned skin which covers windows in the two shell halves. The skin allows temporary outward bulging by elasticity, and immediately springs back into the initial unloaded state at the time the bulging load is removed.

An organizer includes a body adapted to receive and hold a head of a tool and a joining feature provided to the body. The joining feature is adapted to allow interconnection of two or more bodies and includes a complementary protrusion and socket arrangement configured to pivotally couple together by a push fit arrangement of the protrusion from a first body into a socket of a second body. The organizer may further include means for biasing two adjacent, coupled bodies in a pre-established relative orientation.

A key holding device with a top cover plate, a bottom cover plate, a plurality of spacer members, a slide pin and a pair of threaded retaining fasteners. The spacers are sized to fit within the aperture of a standard key. The pair of threaded retaining fasteners are sized to fit within the spacers. The top and bottom cover plates each have matching through channels that engage the slide pin. The keys are retained within the top and bottom cover plate and the slide pin capable of moving the keys out of the perimeter of the top and bottom cover plates so that a person can have access to them. A preferred embodiment includes flat discs fixedly attached to the slide pin so that the slid pin remains substantially upright during the sliding action.
