A hand tool for providing an optical fibre with an end face which is flat and lies in a plane radial to the fibre axis comprises four elongate members extending side by side. The first member is of tubular form and surrounds the other three members and has, mounted near one of its ends, jaws of two pairs of jaws transversely spaced on opposite sides of the longitudinal axis of the member and, between the jaws, a table having a curved surface. The second member is pivotally connected to the first member at its end remote from the table about an axis extending transversely of the members, is urged away from an internal surface of the first member by a leaf spring and carries, near its other end, the other jaws of the transversely spaced pairs of jaws. The jaws of one pair of jaws are mounted to exert a tensile force on the fibre. The third member is pivotally connected to the first member at its end remote from the table about an axis extending transversely of the members, is urged away from the first member by the leaf spring and carries near its other end an elongate cutter. The fourth member is pivotally connected at one of its ends to the first member and has an intermediate part that causes the third and second members to pivot against the action of the leaf spring.
