Sometimes I get home late from an evening out and just need a light snack. I usually have a block of some hard cheese around like cheddar or manchego. But dragging a cold block of cheese from the fridge and using a kitchen knife on it is a disheartening experience -- even though I have good knives.. Maybe I just need better knife skills, but I would actually use something that slices hard cheese thinly and accurately.
I never thought I'd say that, because, historically, I generally hate cheese slicers. Maybe I've never had a good one.
The benefit of thin slicing, of course, is that it speeds up the warming process of the cheese, therefore making it tastier without having to leave it on the counter for an hour.
