A letter opener pen includes a pen barrel, a cap removably attached to the barrel, a clip mounted to the clip, and an U-shaped resilient leaf arranged between the cap and clip to serve as a paper-cutting device. The resilient leaf is of a U-shape having two legs attached to the cap and the clip, respectively. The legs have opposite ends defining a U-shaped opening facing upward, which induces a spring force to bias a lower end of the clip against the cap to provide the clip with a gripping force that secures the pen to for example a pocket. The end of one leg of the U-shape is bent to form a cutting edge, which can be used to cut or trim a piece of paper or to unseal an envelop by placing the piece of paper of the envelop in the U-shaped opening and applying a pressure to the clip to press the cutting edge against the paper or envelop.
A letter opener pen comprising a writing instrument having a body to which a clip is mounted, and a U-shaped resilient leaf arranged between the body and the clip, wherein the leaf comprises two legs attached to the body and the clip respectively, the legs having opposite ends defining a U-shaped opening, the end of one of the leg forming a bent sharp edge serving as a cutting edge.
