Description

Karl Heinz Balke, 565 Solingen 19, Schubertstiaße 4 a Household or professional knife

The invention relates to a household or professional knife with cutting teeth formed by reciprocal millings, which form a cutting edge on both sides, wherein they are replaced laterally to each other like the teeth of a saw ▼.

Such knives are known · They have the cutting properties of a saw with set teeth and are therefore essential compared to conventional knives Sje can therefore cope with higher loads Special dimensions for cutting deep-frozen goods »The known knives, however, stick due to their acute-angled Design of the cutting teeth a major disadvantage, which can be seen in the fact that when Cutting meat fibers in particular from frozen meat Build up in the tooth gaps by grasping the cutting teeth until the tooth gaps are clogged. That The knife is then no longer functional.

It is the object of the invention, these knives of the opening described genus to eliminate persistent pollution.

The invention is characterized in that each straight edge of the cutting teeth of the knife rises obliquely and the slope of the cutting edge of the one Tendon idkaute of the cutting edge forming the cutting edge is opposite to the slope of the cutting edges of the cutting teeth forming the other cutting edge.

When moving the knife back and forth, practice alternately the cutting teeth forming one cutting edge of the knife make a drawing cut and the cutting teeth forming the other cutting edge of the knife make a saw cut the end. While meat fibers, in particular, stick to the gaps in the cutting teeth of the knife, which cut through a S,, when a pulling cut is made, the meat fibers are inevitably drawn out Tooth gaps pulled out. The meat fibers therefore no longer build up in the gaps between the teeth as before, see above that the knife is functional.

In the drawing, the invention is on a household or professional knife with reciprocal millings illustrated toothed cutting edges. Ls time t:

The knife consists of knife blade 1 and handle 2. The knife blade 1 has mutually milled millings that are combined into individual groups Cutting teeth 3.4 on. These form a cutting edge on both sides of the knife blade 1 and are of the type The teeth of a saw are laterally offset from one another.

According to the invention, those designated by 5.6 increase Cutting the cutting teeth 3.4 in the direction of the cutting edge at an angle. The slope of the cutting edges 5 of the cutting teeth 3 is related to the slope of the cutting edges 6 of the cutting teeth 4 opposite.

The application of the invention is not restricted to household or professional users, but can also be used, for example, with circular knives.

Claims (1)

Household or professional knives with cutting teeth formed by mutual millings, which form a cutting edge on both sides, whereby they are laterally offset to one another like the teeth of a saw, characterized in that each straight cutting edge (5 or 6) of the cutting teeth (3 or rises obliquely 4) of the blade and the pitch of the blades (5) of the "ine cutting edge of the knife-forming cutting teeth (3) with respect to the slope of the cutting edges (6) of the other cutting edge forming the cutting teeth (4) is opposite.
