Description

Die Handhabung des Messers ist, weil es beliebig kurz gefaßt werden kann und der Griff immer eine gleichmäßige Auflage für Finger und Hand bietet, eine sehr sichere; dadurch werden Verwundungen von Fleischteilen vermieden und die erhärteten Hautteile vollkommen beseitigt.The handling of the knife is because it can be summed up arbitrarily and the The grip always offers an even support for fingers and hand, a very secure one; this avoids injuries to meat parts and the hardened skin parts completely eliminated.

Durch den unvermittelten Übergang des Stahlgriffes in das Messer wird erreicht, daß das Messer durch Schleifen immer wieder die ursprüngliche Form erhalten kann, daß also der Operateur stets in genau derselben Weise das Messer halten und benutzen kann, wie er es von Anfang an gewöhnt ist.The sudden transition of the steel handle into the knife achieves that the knife can always get its original shape by grinding, so that the surgeon can always hold and use the knife in exactly the same way as he can it is used from the start.

When cutting corpse thorns Both knives are usually used, and it is therefore from. special Advantage that both are combined with one another on one handle.

Fig. Ι is the side view of a knife, which has a cutting edge at both ends.

Fig. 2 is the top view of the knife.

FIG. 3 is a longitudinal section along AB in FIG. 2.

Fig. 4 is a cross section according to CD in Fig. I. . ■

Fig. 5 is a cross section according to EF in Fig. I.

α is the surface of the knife recessed by a hollow grind in the transverse direction;

b is the convex ground side of the same; ^

c is the slightly curved cutting edge;
d is the surface of the spoon-like knife recessed by grinding in the transverse and longitudinal directions;

e is the convex ground side of the same;

/ is the rounded tip of the same.
