The most dangerous item in your kitchen, excluding a toaster with a bagel stuck in it, is the knife, each kitchen containing dozens of them, and each knife made hazardous by its sharp blade. Ironically, however, the name of this sharp and deadly component—the blade—derives from an Indo-European source, pronounced something like bhlo, that meant flower. This Indo-European source evolved not only into the word blade but also into blossom and even, thanks to successive sound changes, into the word flower itself. When blade appeared in English in the early eleventh century it referred only to the narrow leaf of a plant; it was not until the fourteenth century that the word was also transferred to the narrow, leaf-shaped length of a knife.
