I thought it would be a great wallet pocket, but my wallet has too many store cards, loyalty cards, breakdown cards, business cards, receipts, a trolly coin, and a photo of my T6, so it won't fit, even though I have tried, and lost the odd knuckle or two whist trying.
It would make a great block of cheese holder, and each time you pull out the cheese, the sharp edge will cut off a perfect cheese slice, hey presto, instant sandwich filling..
