There are seemingly endless gadgets to assist in enjoying a slice of cheese. This stainless steel cheese holder from Swissmar is designed to grip a hunk of cheese without breaking it (as can often happen with knives, toothpicks, or forks) while you slice a piece off for yourself. Necessary? Probably not. Courteous to have when throwing a big party with a slice-it-yourself cheeseboard? Definitely. See the product review on Serious Eats below.
It’s not a big deal to touch a hunk of cheese with your (clean) bare hands if you’re making grilled cheese sandwiches for the family, right? But if you’re serving guests or have a cheese board set up where guests can slice cheese for self-serve, they might be happier not to have everyone’s fingerprints all over every wheel and brick of cheese on the board.
