Type of bronze dagger found in the ESSEX I Phase of the early Bronze Age (c.1700-1500 BC) in southern Britain which has similarities with examples from Brittany. It has a flat triangular blade, lateral grooves, and six rivets for attaching the blade to the hilt. Sometimes a small tang or languette is present to assist securing the blade to the hilt. Traces of wooden and leather sheaths have been found with some blades; the hilts were probably of wood and in the case of an example found in the Bush Barrow, Wiltshire, were inlaid with gold tacks.
