Letter opener

Abstract

A letter opener (100). Letter opener (100) comprises a main body (102) having an open side, a covering piece (104) for closing up the open side of main body (102), a cutting blade (106), made of a ceramic material, rotatably installed inside main body (102), a spring member (108) installed inside main body (102) for maintaining blade (106) in position and for countering the rotation motion of blade (106) when blade (106) is in cutting mode. On the upper portion of main body (102), there is provided a lip piece (110) having a lower straight surface extending laterally. A through guide groove (112) is formed in between lip (110) and the upper surface of covering piece (104). Blade (106) extends upward across substantially groove (112) at a substantially right angle. When letter opener (100) is sliding along a marginal edge of a letter, cutting blade (106) operates to pierce through one layer of the letter and to cut a cutting line thereon, which is generally parallel to and offset by a slight spacing from the edge of the letter. Letter opener (100) is convenient and safe to use and is of durable construction.
