A butter knife, or properly called a butter spreader, is a type of table knife which is built with a round, dull, non-serrated blade edge. It is primarily used for applying butter and other soft or viscous spreads to slices of bread or pastry. In formal culinary terms, a master butter knife is a sharper-tipped, saber-like knife which transfers butter from a central butter dish to the plates of diners, and then the more familiar rounded individual butter knife which this article will focus on is used to transfer the butter to its final destination upon a piece of bread.
