There was a hush around the room when the Queen placed her open palm on the sharp side of the blade, but thankfully no rush to the emergency room was needed.
"That looks very good," Queen Elizabeth stated proudly once they were finished. The video collected millions of views on social media overnight, once again proving the public interest in watching the royal family perform everyday tasks remains high.
The lunch was organised by The Eden Project, an educational charity that brought the Queen and the Duchesses face-to-face with local volunteers from the Cornish community during the Covid-19 crisis.
Queen Elizabeth's appearance at the event was only the second since her husband, Prince Philip's, funeral in April. The first was on May 11 at the State Opening of parliament.
The appearance was also the first since the news of Prince Harry and Meghan Markle welcoming a daughter named after the Queen's beloved nickname, Lilibet. As Page Six previously reported, the Queen has already met her newborn namesake and great- granddaughter over Zoom.
This weekend is the Queen's Jubilee, a celebration in honour of the Monarch's birthday, which was actually on April 26. The Eden Project's lunch event was just one to kick off the festivities, which will include a parade at Windsor Castle on Saturday, June 12.
Sadly, this is the Queen's first Jubilee weekend without her husband, Prince Philip.
Viewers commented in droves asking why the 95-year-old was holding the sword upside down.
"It is old-school tradition to cut a cake with a knife upside down. It is for good luck. That lady knows more than you," Twitter user Matthew Hallwor responded. Others were just impressed the Queen was able to pull off the entire stunt without removing her handbag.
