The invention relates to a handle for knives, in particular knives for the butcher's trade.

In the case of handles for knives that are used in the butcher's trade, it is known to be on the side in the area of both ends Provide widenings so that the hand is prevented from sliding in the longitudinal direction of the handle even if there is fat on the handle or the palm of the hand, which is what is expected in the butcher's trade got to. For the same purpose it is also known to provide downwardly projecting noses at both ends. A twisting motion however, the grip in the user's hand cannot be prevented in this way. Also a roughening of the two The side surfaces of the handle are generally not sufficient to allow the handle to rotate in the hand of the user to be able to hold on securely.

The invention is based on the object of providing a handle for a knife which can be held more securely can, than is possible with the known handles, especially when on the handle or the The palm of the user is fat. This object is achieved in that the back in his Central section has a polygonal profile.

Such a polygonal profile in the middle section of the back of the handle prevents to a sufficient extent a rotational movement of the handle about its longitudinal axis relative to the hand of the knife user, since those formed by the polygon run at least substantially in the longitudinal direction of the handle Edges ensure a good hold. It is also advantageous here that the polygonal profile give the handle a pleasing appearance.

These advantages are particularly evident when, as is the case with a preferred embodiment, the back has three flat surfaces, of which the middle surface lying perpendicular to the longitudinal center plane of the handle by two straight lines that run symmetrically to the longitudinal center plane and meet in the area of the free end of the handle Edges is limited laterally, which is immediately followed by one or the other side surface, the both have the same shape and size, each include an obtuse angle with the median plane and like that middle surface are laterally bounded by two straight, an acute angle forming edges, but the point lies at the end portion of the handle adjacent to the blade of the knife.

In order to prevent one of the fingers from being placed on the back of the knife blade, the back of the Handle on the end of the blade adjacent to a hump. Appropriately, it has to be on the middle area subsequent flank of this hump has a lower steepness than the other flank. This allows the cusp to be very close to the Handle end are arranged.

IV r ^ W bm ^ V ~ -y b7M.yi _- yi of Fig.

A handle for a knife, designated as a whole by 1, consists in the exemplary embodiment of plastic and is formed in one piece. The attachment part of the blade 2 is embedded in the handle 1. As FIG. 3 in particular shows, the handle is designed symmetrically to the longitudinal center plane of the knife in which the blade 2 lies. On the two side surfaces 3 and * \ , in the area of both end sections of the handle 1, laterally protruding contact surfaces 5 adjoin, which prevent or at least limit a displacement of the handle 1 in the hand in its longitudinal direction. The same purpose are used downwardly extending projections 6 and 7 in the region of the rear and front end of the handle 1. The height of the

Projection 7 is always chosen so that ^ I._ ~ H. ΓΖ.ΖΓ ~~ "H ~ '

j the blade 2 is completely covered so that on your fingers cannot get into the area of the cutting edge of the blade.

A bump 8 on the projection 7 opposite side of the front end of the handle 1 prevents a top gripping / - \ 1 of the handle with the thumb or a finger.

To about its longitudinal axis to prevent rotation of the handle 1 relative to the hand holding the hand, the back in its central portion which lies between the two projections 6 and 7, forming end portions, a polygon profile, as Fig. 4 1 to 6, "the back" being formed by a central surface 9 and two lateral surfaces 10 and 11, respectively. All three surfaces are flat. The middle surface 9 is symmetrical and perpendicular to the longitudinal center plane of the handle 1. The two lateral surfaces 10 and 11 are also symmetrical to the longitudinal center plane and each form the same angle with the central surface 9. In the exemplary embodiment , it is an obtuse angle.

As FIG. 3 shows, the middle surface 9 is delimited by two at least essentially straight edges 12 which meet in the region of the free end of the handle. The end of the middle surface 9 opposite the tip merges into one flank of the hump 8, the other flank of which is steeper. The two lateral surfaces 10 and Ii are delimited by the edges 12 and edges 13 or V \ and have a shape very similar to the central surface 9, but widening from the front end section to the rear end section of the handle 1 Profile of the back of the shape shown in Fig. 4, in which the two lateral surfaces 10 and 11 appear only as lateral bevels of the otherwise flat back, over a polygon with essentially equally long sections between two corners in the area of the transition of the middle section of the handle to the widened rear end section into a polygon which is essentially formed by the two lateral surfaces 10 and 11 and therefore has a corner lying in the longitudinal center plane of the handle.

To increase the grip even further, are the both side surfaces 3 and U with a not shown / "'Roughened.
