Query: this is a JOKE!

This "cheese knife" is a joke. True, the cheese will not stick to the plastic blade. But, it is impossible to achieve a thin slice of cheese. I usually buy Vermont Cabot extra sharp cheese in two pound blocks. The blade is design so it is fairly thick and it will break extra sharp cheddar rather than slice it. Back to a really thin blade on a knife I was given at a car dealership!
