English: A cast copper-alloy hook-piece from a Anglo-Saxon sleeve or wrist clasp of Hines’s Form B20 (plate and bar cast in one piece). The differentiation between the plate and the hook on this clasp is very slight.

The plate consists of four lobes down the rear edge. The central two are triangular, whereas the lobe at either end is more rounded, and is perforated with a circular sewing hole (one of which is now incomplete). Each lobe is decorated with a narrow groove along either side (drawn rather aslant on one of the end lobes) and the central lobes also have a row of three crescentic punchmarks running from base to apex. These punchmarks have been made by holding a circular punch at a slight angle.

The bar area is slightly raised, and begins towards the rear with a longitudinal row of punched dots. The front edge has three slightly raised long and narrow panels, and a second longitudinal row of punchmarks runs down here, over the panels at either end but leaving the central panel untouched; the decoration here consists of a transverse groove at either end and an oblique groove joining the two. The punchmark used here consists of a short row of double dots. The hook is cast in one piece with the rest of the clasp, in the centre of the reverse. The clasp measures 36.5mm in length and 12mm in width. The catch element is cast in one with the bar. Early Anglo-Saxon, late fifth or sixth century.
