The invention relates to a utilitarian swinging knife. According to the invention, the knife, in a first embodiment, consists of a handle made of reliable material, consisting of an upper semicasing (1), a lower semicasing (2) with a longitudinal lamellar plate (3) gliding therebetween, said plate being sharpened at the ends, having the ends in the shape of a symmetrical ogive and a groove (h) with a width (p) larger than a diameter (D) practiced axially longitudinally in the lamellar plate (3) with a width (t), each end having a double cutting edge, the lamellar plate (3) whose length is substantially smaller than the length (L) of the two semicasings (1,2), all these three pieces being possible to be tightened by means of a special screw (4) located in the middle region of the handle, conventionally on the left side in relation to the transverse symmetry axis (w-w) which can pass through an orifice (f) in the lower semicasing (2) and through the groove (h) of the lamella (3), being screwed in a thread (g) machined in the upper semicasing (1), upon unscrweing this special screw (4), the lamellar plate (3) being capable of gliding, by shaking or orientation by the hand, by the play between the semicasings (1, 2), towards any of the handle ends, on a maximum distance ( &sgr; ), the position of the lamellar plate (3) being adjusted according to the user's need and secured by screwing in the special screw (4), at both ends, both semicasings (1, 2) having provided a flat bevel (n) in order to allow the lamellar plate (3) to move elastically without tensioning, according to an angle ( &egr; ), both semicasings (1, 2) having from moulding or by machining some recesses (I), a penetrated recess and an unpenetrated recess. |
