A compact, ergonomic, pocket-sized bottle opener having a thin, generally flat body. The bottom edge of the body includes a jaw opening and at least one area for receiving a lifting finger. A plug of resiliently yielding material is mounted in the finger-receiving area to cushion the lifting finger. A hook at the forward end of the jaw opening forms a fulcrum point for engaging the top of the bottle cap. The hook also serves to lift pull-tabs on cans. An opening at the rear of the body holds a key ring. The key ring can be slipped into the opening during assembly by flexing the leg so as to open a slot that separates the distal end of the leg from the body. The cushioning plug mounts over both the distal end of the leg and the lower edge of the body so as to hold the leg in place after the ring has been installed. The two sides of the body form broad, generally flat display surfaces for application of logos, advertising, or other information. The body is preferably formed of strong, molded plastic, with a metal insert being installed in the jaw opening for engaging the edges of bottle caps.
