A hand tool comprising: an elongate body; a nut turning means at a first end of the body; and a top cap and a bottom cap disposed on opposite sides of the body; wherein the top cap and the bottom cap are secured to the body by an interconnection (311 a,314a; 311 b,314b; 311 c,314c; 311d,314d) between the top cap and the bottom cap which traverses at least one hole (315a,315b,315c,315d) formed through the body and wherein the top cap, the bottom cap and the body combine to form a gripping portion suitable for use as a handle, wherein the interconnection comprises at least one pair of dowels (311a,314a; 311 b,314b; 311 c,314c; 311 d,314d), wherein one of each pair of dowels (311 a,311 b,311 c,311 d) protrudes from the top cap to engage the other of each pair of dowels (314a,314b,314c,314d) which protrudes from the bottom cap, and wherein the or each pair of dowels traverses a respective hole (315a,315b,315c,315d) through the body, characterised in that the hand tool comprises an electronic identification device, wherein the electronic identification device is encapsulated in a cavity defined by the body and at least the top cap, wherein at least the top cap comprises a material which is at least partially-transparent to radio frequency energy in order to facilitate transmission of signals to and from the electronic identification device, wherein the interconnection comprises a multitude of pairs of dowels (311a,314a; 311b,314b; 311c,314c; 311d,314d) and wherein different widths (W2, W3) between adjacent pairs of dowels preclude rotational symmetry of the top cap and the bottom cap about their midpoint. an elongate body; a nut turning means at a first end of the body; and a top cap and a bottom cap disposed on opposite sides of the body; wherein the top cap and the bottom cap are secured to the body by an interconnection (311 a,314a; 311 b,314b; 311 c,314c; 311d,314d) between the top cap and the bottom cap which traverses at least one hole (315a,315b,315c,315d) formed through the body and wherein the top cap, the bottom cap and the body combine to form a gripping portion suitable for use as a handle, wherein the interconnection comprises at least one pair of dowels (311a,314a; 311 b,314b; 311 c,314c; 311 d,314d), wherein one of each pair of dowels (311 a,311 b,311 c,311 d) protrudes from the top cap to engage the other of each pair of dowels (314a,314b,314c,314d) which protrudes from the bottom cap, and wherein the or each pair of dowels traverses a respective hole (315a,315b,315c,315d) through the body, characterised in that the hand tool comprises an electronic identification device, wherein the electronic identification device is encapsulated in a cavity defined by the body and at least the top cap, wherein at least the top cap comprises a material which is at least partially-transparent to radio frequency energy in order to facilitate transmission of signals to and from the electronic identification device, wherein the interconnection comprises a multitude of pairs of dowels (311a,314a; 311b,314b; 311c,314c; 311d,314d) and wherein different widths (W2, W3) between adjacent pairs of dowels preclude rotational symmetry of the top cap and the bottom cap about their midpoint.
