Abstract: A new wellbore cutter has been invented which, in certain embodiments has a piston having a fluid flow bore therethrough, at least one stabilizer kick-out member, and at least one cutting blade kick-out member, an outer body through which the piston projects, the outer body movable about the piston, the outer body having at least one stabilizer pivotably mounted thereto, the at least one stabilizer movable out from the outer body upon movement of the outer body with respect to the piston so that the at least one stabilizer contacts the at least one stabilizer kick-out member, said contact effecting extension of the at least one stabilizer out from the outer body, and the outer body having at least one cutting blade pivotably mounted thereto, the at least one cutting blade movable out from the outer body upon movement of the outer body with respect to the piston so that the at least one cutting blade contacts the at least one cutting blade kick-out member, said contact effecting extension of the at least one c
