ABSTRACT:
A letter opener includes a handle portion, a depending neck portion, and oppositely extending tine portions carried by the neck portion. A cutting edge is mounted on each side of the neck portion such that either of the tine portions can be inserted under the flap of a sealed envelope and moved across the envelope to permit the respective cutting edge to slice open the envelope. Since the novel letter opener according to the invention includes two cutting edges, the useful life of the letter opener is doubled over the useful life of prior art, single cutting edge letter openers. Inasmuch as the letter opener may carry one or more informational messages, such as advertising messages, postal rate information, etc., the length of time the messages are exposed to the user is also doubled, thereby doubling the value of the letter opener to both the user as well as those employing the letter opener as a medium of communication to the user.
