Die Erfindung betrifft ein Messer mit einem Gehäuse (11, 111) und mit einer Betätigungsvorrichtung (13, 116) zur Bewegung eines Klingenträgers (14) oder eines Klingenschutzes (113) zwischen wenigstens einer Sicherheitsposition und wenigstens einer Schneidposition, wobei die Betätigungsvorrichtung (13, 116) eine Handhabe (12, 117) umfasst, wobei mittels der Betätigungsvorrichtung (13, 116) eine Bewegung der Handhabe (12, 117) auf den Klingenträger (14) oder den Klingenschutz (113) übertragbar ist, umfassend eine der Handhabe (12, 117) zugeordnete erste Betätigungsfläche (23, 123) und eine dem Klingenträger (14) oder dem Klingenschutz (113) zugeordnete zweite Betätigungsfläche (19, 125). Die Besonderheit besteht darin, dass eine der Betätigungsflächen (19, 125) als Steuerfläche mit wenigstens zwei unterschiedlichen Steuerbereichen (20, 21, 126, 127). ausgebildet ist.
摘要:
According to a first aspect, the invention relates to a cutting tool, in particular for severing planar materials, such as paper, cardboard, films, strips, and mats, as well as bands, ropes, and similar material, comprising a gripping area and a tool head (23), wherein a guide channel (24) is formed between guide surfaces (25a, 25b) of the tool head (23), wherein the material to be cut can be fed to the cutting edge (S) of a blade (15) only through the guide channel (24). The invention is characterized in that the blade (15) can be moved between a safety position, in which a cutting edge (S) of the blade (15) is protected by a cover so as to be inaccessible to a user, and a cutting position, in which the cutting edge (S) is accessible only through the guide channel (24).

The corkscrew according to the invention, which has the basic structure of a conventional corkscrew, comprising a helix (1) which fits into a handle (3) with a grooved configuration so that, in the operating condition of the helix (1), it may remain partially engaged within the grooved part of the handle (3), said handle (3) being hinged at one of its ends on a support arm (5), is principally characterized in that the handle (3) incorporates a metal core (7) with a basically U-shaped cross section, housing internally a longitudinally displaceable capsule-cutting knife (10) capable of protruding externally from the handle (3) and with a blade extended at the rear in the form of a widened segment (11) acting as a guide, having a lateral projection (12) protruding towards the outside of the handle (3) through a longitudinal groove (13) along which it is displaceable with the aid of the user's finger. In this way the knife may be easily extracted using only one hand.

A retractable knife (10) includes an elongate handle (11) and a blade holder (22) slidingly mounted within the handle for sliding movements between a retracted position and an extended position. The blade holder is configured for receiving a blade (24). A manually operable blade lock is formed on the holder and including a release member (32) rotatably mounted on the blade holder. The release member having a first portion (32a) projecting beyond the handle and positioned to be actuated by a finger of a user while holding the handle. A second portion (44) is movable with the first portion between a locking position in which the second portion is received with a notch (24c) of a blade (24) and a releasing position in which the second position is removed from the blade notch to a position outside the notch of the blade. A spring (40) normally rotates the release member to move the second portion to the locking position. Actuation of the release member by the finger of the user to overcome the spring moves the second portion to the releasing position and releases the blade.

Knife for skin-diving activities, comprising a blade (1), a tang (2) extending from said blade (1), and a tubular member (4) inserted over said tang (2) and adapted to be slid from a first position wherein it covers said blade (1), to a second position wherein it covers said tang (2) and uncovers the blade (1). The blade (1) and the tubular member (4) are provided with co-operating releasable locking means (204, 304, 504) for firmly holding said parts in both said first and second positions. The knife is equipped with means (6, 201) for connection in a quick-releasable manner to a strap of a skin-diver's equipment as, for example, to his belt.
