Could someone please explain how the cheese knife is supposed to work? I get the idea that you are supposed to be able to slice normally or use like a cheese plane, but I have had ZERO success with it so far. I have to push down on the top of the knife to get it to go through cheddar-- that hurts! Why would I want a knife that hurts? Am I just using it wrong? Also, the Deluxe Cheese Grater... Does anyone have a problem with the cheese gumming up the grater? I think it would work for very hard cheeses like parmesan, but using it on cheddar gets to be pretty difficult. My hand gets tired from squeezing the handle so hard, but if I don't then the cylander rolls around without grating anything. Then, once I get some cheese grated, it all gums up inside the barrel of the cylander and is EXTREMELY difficult to clean. I am having a hard time feeling very good about reccomending these products-- how do they work for all of you? PS Sorry about my awful spelling. It's very late!
