A cheese plane ? I know, it doesn't seem like the most crucial tool to have in the kitchen. But after living in Scandinavia, where every kitchen has one on hand, I came to appreciate their importance. No other implement makes such perfectly thin leaves; it's the optimal way to enjoy flavorful, semi-hard cheeses like gouda and Swiss. Big wedges can go a long, long way when you slice them that thinly, which makes the tool excellent for party cheese platters. But my favorite way to use it is for a humble breakfast sandwich of a fruit-and-nut hard roll with cheese and cucumber. The one with the clear handle belonged to my roommate's grandmother who bought it in the '60s.
