Savoir Vivre One Size Oyster Glove.
This slinky accesory looks like chain mail and is indeed the first line of defense against the knife in your other hand trying to worm its way inside the clasp of the mollusk. Knit with tiny, interlocking metal links and designed to fit either hand, this mesh glove is intended for use with oysters but would be suitable for any operation that requires hand protectionsuch as boning or filleting meat or fish, or even just slicing bagels..
