A hand tool is disclosed for rapidly recovering an extensible and retractable antipersonnel barrier of helical barbed tape. The hand tool includes first and second elongated parallel gripping arms joined at one end by a base section. Each of the elongated gripping arms includes an L-shaped rigid safety barrier defined by a forward guard rail and an elongated lateral guard rail. The distal end of each of the elongated lateral guard rails is disposed intermediate the base section such that the lateral guard rails are parallel to the elongated gripping arms. The distal end of each of the forward guard rails are disposed at the distal end of each of the elongated gripping arms respectively, thereby defining a pair of generally rectangular zones of safety. The hand tool further includes a telescoping engaging arm which comprises a fixed outer tube and a removable elongated inner tube. The inner tube is connected to the fixed outer tube by a bayonet-type locking mechanism. During a rapid recovery operation the rigid safety barriers preclude the razor sharp barb clusters on the helical barbed tape barrier from coming into contact with the hands of the user, thereby preventing severe injuries. The inner tube of the telescoping engaging arm can be easily removed so as to facilitate convenient storage of the tool in a desired container.
