I remember coming to the rescue of a chap who’d cut his hand really badly trying to open oysters with an ordinary knife on a Eurocamp holiday when the children were small. My first aid kit was even more extensive in those days! It stuck in mind because they were Jewish, I did question the oysters, he said he sometimes cheated on holidays much to the disgust of his strictly Kosher wife. I doubt he did again as she barely spoke to him for days!A gift of a folding bucket nine years ago and an oyster opening knife - haven't used either of them.
