Embodiment Construction

[0014] The handle 1 of the knife has a metal tang 2 integrally formed on the metal blade, which is covered on both sides as a flat iron by two plastic handle shells 3 . Here, the tang 2 can be visible on both sides of the handle, or can also be covered there by a handle shell, so that the tang is not visible.

[0015] The plastic of the handle 1 and thus the handle shell 3 form a cylindrical opening 4 in the form of a hole at the end of the handle, into which a metal pin 5 of a metal end cap 6 is positively inserted, wherein the pin 5 is integrally formed on the end cap and the end cap 6 covers the plastic at the end of the handle. In this case, the outer diameter of the cylindrical pin 5 corresponds to the inner diameter of the opening 4 , so that the pin 5 is inserted into the opening 4 with a positive fit, in particular a frictional fit.

[0016] The end of the pin 5 facing the stem 2 has a recess 7 which bridges the stem 2 in a form-fitting manner. In this case, the open...

Abstract

The present invention relates to a knife having a metal blade and a tang (2) formed integrally on the blade, wherein, the tang serves as a flat iron to support a handle (1) made by plastic; a metal end cap (6) is fixed at a handle end; the plastic on the handle end is provided with an opening (4), the opening is leaded to a tang end; the metal end cap (6) has an integrally formed bolt pin (5), the bolt pin is inserted into the opening (4) in a locking way, the bolt pin (5) has a gap (7), especially a transverse seam, at an end facing the tang end, and the bolt pin is in bridge connection with the tang end in a locking way through the gap / transverse seam.

Description

technical field [0001] The invention relates to a knife with a metal blade and a shank (Erl) integrally formed on the blade, which supports a handle made of plastic as a flat iron, wherein a metal handle is fastened to the end of the handle end cap. Background technique [0002] Known metal end caps for knife handles are produced by forging the end cap on the shank. Alternatively, it is known that a metal end cap is manufactured as a casting and welded onto the tang end. Both manufacturing methods are labor intensive in manufacturing and fixing. Contents of the invention [0003] The object of the present invention is to fasten the metal end cap in a simple and reliable manner, in particular to fit securely and reproducibly, in a knife of the type mentioned at the outset, and thereby to enable rapid further processing of the knife. A precise rotational position of the end cap should also be ensured. [0004] According to the invention, this task is solved in that the p...
