Abstract
A letter opener for cutting open an envelope comprises a channel-shaped blade holder having a pair of manually-movable arms and a cutting blade mounted on one of the arms. The blade holder closely embraces opposite sides of a marginal edge region of an envelope to be opened, as well as a longitudinal edge thereof. The cutting blade is operative to pierce through at least one layer of the marginal edge region, and to cut a longitudinally-extending cutting line which is generally parallel to, and offset by a slight spacing from, the longitudinal edge when the holder is guided along the longitudinal edge.
