发明名称 METHOD OF MAKING A KNIFE WITH AN OBLIQUE BOLSTER
摘要 The invention relates to a method for producing a knife (1) with a blade (2), a bolster (3) and a handle, in particular a tang (4), forged from a single piece of flat steel material (5), wherein, before forging, the flat material (5) is upset in the region between the blade (2) and the handle or tang (4) to form a bead (6), the longitudinal axis (LW) of which is arranged transversely in relation to the longitudinal axis (LM) of the knife, and is then formed by forging to form a bolster (3), which has at least one side edge (K2) positioned obliquely in relation to the longitudinal axis (LM) of the knife, wherein the longitudinal axis (LW) of the bead (6), which later forms the bolster, is oriented obliquely in relation to the longitudinal axis (LM) of the knife (1).
