Abstract: A screw cap remover having an elongated handle, a first semicircular jaw secured to a first end of the handle, and a second semicircular jaw axially slidable along the handle. A tubular sleeve slides along the elongated handle and has the second jaw secured at a first end thereof. The second end of the sleeve is adapted to abut against a rotatable cam member, the rotation of which axially displaces the tubular member and thus, the second jaw, toward the first jaw. The rotatable cam member is adapted to be positioned at several discrete positions along the elongated handle and the jaws are detachably secured to the handle so that jaws of a size corresponding to the size of the screw cap can be easily installed or replaced.
