An electrosurgical pencil comprises a main body portion forming a handle. A wire retaining passage is defined by the main body portion and has a wire-receiving opening and an electrode-receiving opening. A metal electrode tip is mounted at the electrode-receiving opening for engaging tissue in a surgical site to thereby coagulate the tissue. A wire enters the wire retaining passage is selectively connectable in electrically conductive relation through an electrical switch to the metal electrode tip. A substantially unobstructed airflow vent is defined substantially solely by the main body portion so as to extend from the electrode end to the exhaust end of the main body portion, and has an inlet disposed adjacent the electrode end of the main body portion and that is connected in fluid communication via the airflow vent to an outlet disposed adjacent the exhaust end of the main body portion.
