Photos: Queen Elizabeth pictured using a ceremonial sword to cut a cake during a royal engagement

Queen Elizabeth was caught on camera using ceremonial sword to cut a cake during a royal engagement. 

The 95-year-old Monarch carried out a rare joint engagement with the Duchesses of Cambridge and Cornwall at the Eden Project in Cornwall yesterday

The three most-senior royal women attended the event in celebration of The Big Lunch, which will form part of the Queen's platinum jubilee celebrations in 2022.

The Queen was presented with a large cake and was handed a sword by Edward Bolitho, the Lord-Lieutenant of Cornwall, to cut it. 

When told by an aide that there was a conventional knife available, the Queen replied: 'I know there is, this is more unusual'.
