I do not know what you mean by raw butter: no butter is cooked. If you mean unsalted butter, it will likely go bad more quickly because salt is a preservative. But typically, all butter lasts longer in a french butter dish (also known as a butter bell -- it has a section for water, and a section for the butter).
Do you mean 'synthetic' butter? And by rancid do you mean it doesn't taste as good as cow's butter? If so, simply because synthetic butter is generally a mixture of oils, water and flavorings. Butter is made from cream which comes from cows.
Do you mean knife? If so then the plural of knife is KNIVES. hope that helped. Bye!
