<p>Pliable tool, in particular knife (1), with locking system of the "liner-lock" type, in which in the end portion of the heel (6) of the blade (2) a recess (5) is provided, in which the liner (3) of the tool is en¬ gaged for locking the blade (2). According to the invention, the recess (5) is made with a profile which is perpendicular to the horizontal surface of the blade (2), in a manner that in the operative position of the blade (2) a minimum space (8) remains between the recess (5) and the liner (3). The tool also comprises a pitch recovery system of the blade (2), consisting of a pin (9) slidable into a guide member (10) provided in the grip (11) and another guide member (12) provided in the back half-liner (4), which guide members are inclined to each other, so that, when the pitch recovery system isn't activated, the pitch of the blade (8) is determined owing to the presence of the space (8), while when such system is activated, the space (8) doesn't exist anymore, so that the liner (3) is brought into full contact with its seat in the recess (5), and the pitch of the blade (2) is absent.</p> |
