Industrial phase of the British Bronze Age immediately following the Knighton Heath Period. Named after a hoard of bronze tools and weapons found in a quarry at Penard, West Glamorgan, in South Wales in 1827, the tradition spans the period 1200 bc through to 1000 bc. During this time there was much experimentation in metalworking, stimulated by contact with Urnfield Tradition smiths in northern and central Europe. Among imports in the period are early styles of sword and perhaps shields. Inventions include cylinder sickles and leaf‐shaped pegged spearheads. Sheet metal became more extensively worked than in earlier phases, and there was increasing use of clay moulds and more lead‐rich alloys.
