Letter Opener

A letter opener, or paperknife, is a knife-like object used to open envelopes or to slit uncut pages of books. Electric versions are also available, which work by using motors to slide the envelopes across a blade. These have the advantage of being able to handle a greater volume of envelopes, but the blade can slice into the contents of the envelope and damage them.

Letter Openers

Letter openers may be composed of wood, metal, plastic, or a combination of materials. Some modern openers have a hidden razor blade inside a plastic handle. In any case, the constant cutting of paper will eventually wear down cutting surfaces, requiring either sharpening or replacement. Conventional letter openers can also be used as a weapon for assault or self-defense, depending on the situation.
