A twist-drivable pin assembly includes first and second drivers, each having a driving end which can be received in a bore in the end of a twist-drivable pin, and an opposite end at which torque can be applied. The cross-sectional shape of each of the drivers at its driving end has a first plurality of apexes whose relative locations coincide with the apexes of a regular polygon such as a hexagon. The drivers differ from one another in their cross-sectional shapes at the driving end by virtue of one or more faces of at least one of the drivers between adjacent pairs of apexes having a groove formed in it. Each of first and second twist-drivable pins has a bore extending into it which is defined by a second plurality of apexes arranged as a regular polygon such as a hexagon and which is open at one end.

A composite coating is provided for a tool. The tool can be a pair of scissors or a screwdriver for example. The tool is made with at least one contact face.

Provided is a screw. A recess portion is formed at an end of the screw by extending a depth along a central axis direction of the screw. A tool matching structure is formed on a bottom surface of the recess portion for providing a tool that enters into the recess portion so as to make a part of the tool and the tool matching structure be matched to each other, thereby operating the tool to drive the screw for rotating.

A wallet includes a first shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; and a second shell coupled to the first shell, the second shell including a storage compartment; and first and second rails on each side of the second metal shell to slideably receive one or more cards in the storage compartment.

The multi-tool wrench is a single tool that provides multiple tools useful by a craftsman. The multi-tool wrench comprises a first tool half and a second tool half that are removably coupled by a quick disconnect.
