An amateur detectorist has described how he unearthed a bronze age hoard, including a rare sword, after getting lost during a treasure hunters’ rally.

John Belgrave, 60, became separated from the main group of detectorists and headed to higher ground to try to spot them when he made what he has called the find of a lifetime.

His device activated as he walked along and when he dug down he uncovered a rapier sword dating back to the middle bronze age.

The 61cm (2ft) rapier had been deliberately broken into three pieces and placed in the ground alongside the remains of a wealthy landowner.

Unusually, the hilt, though cast in bronze, was shaped to mimic a wooden handle. Only two similar rapiers have been found in Britain before and they were incomplete.

As well as the rapier, a palstave axe head and a decorative arm bangle were found, presumably buried as an offering.

Dorset Museum and Art Gallery raised £17,000 to buy the objects, with the proceeds shared between Belgrave and the landowner.
