Cheese Wheel is a crafting ingredient that was added in the June 19, 2012 Patch. It appears as a wheel of cheese with a slice cut off. There is a sticker on the side.
Unlike some other items, this item is considered to be not so often found.
Equipping the Eliminating The Impossible set will change the Cheese Wheel description to "may go on... the hidden wickedness...", with random characters removed, which is a part of a quote from the "The Adventure of the Copper Beeches" short story, part of The Adventures of Sherlock Holmes collection. When combined with the other items added in the June 19, 2012 Patch, the full quote reads "Think of the deeds of hellish cruelty, the hidden wickedness which may go on, year in, year out, in such places, and none the wiser."
This currently has no use in the TFHunt solving.
