An angled optical fiber cleaver device operable for cleaving an optical fiber and providing an angled optical fiber endface, the angled optical fiber cleaver device comprising: a retention and rotation clamp assembly; and a cleaving assembly operable for cleaving the optical fiber; characterized in that the retention and rotation clamp assembly includes a fiber clamping arm and a main clamping arm pivotable with respect to one another; the retention and rotation clamp assembly is operable for successively retaining and rotating an optical fiber with a single actuation motion by a user by: the fiber clamping arm being in a first vertical position and the main clamping arm being in a first angled position away from the fiber clamping arm and away from a body of the angled optical fiber cleaver device when the retention and rotation clamp assembly is in a first actuation state, the fiber clamping arm and main clamping arm being configured to receive the optical fiber in the first actuation state; the fiber clamping arm being in the first angled position and the main clamping arm being in the first angled position no longer away from the fiber clamping arm but still away from the body of the angled optical fiber cleaver device when the retention and rotation clamp assembly is in a second actuation state, the fiber clamping arm and the main clamping arm being configured to securely retain the optical fiber in the second actuation state; and the fiber clamping arm being in a second vertical position and the main clamping arm but in the first vertical position still no longer away from the fiber clamping arm but no longer away from the body of the angled optical fiber cleaver device when the retention and rotation clamp assembly is in a third actuation state, the fiber clamping arm and the main clamping arm being configured to rotate the securely retained optical fiber in the third actuation state. a retention and rotation clamp assembly;
