  • Publication number: 20130174696
    Abstract: 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).

  • Publication number: 20120199016
    Abstract: A griddle pan comprises a pan body having sides and an inside bottom defining a perimeter at which the sides protrude upward from the inside bottom. The inside bottom has a center and an upper face on which protrude upwardly rising ribs upon which food to be grilled is laid. The ribs have outside ends disposed at a distance from the sides. The ribs have upper surfaces all lying in a same horizontal, non-curvilinear plane and define intervening spaces therebetween. In the intervening spaces between the ribs, the inside bottom slopes from the center to the outside ends of the ribs and toward the sides.

  • Publication number: 20120124844
    Abstract: A chef's knife comprises a handle and a blade. The blade has a point, sides, and an edge ground on both of the sides to form a cutting edge. The cutting edge has a section near the handle and a section near the point of the blade. The cutting edge has an acute cutting angle ? that becomes continuously smaller from the section near the handle towards the section near the point of the blade.

  • Publication number: 20100000098
    Abstract: The present invention relates to a cleaver (8) having a crush-forged crank (6). In order to provide a cleaver having an improved manageability and surface feel, thereby preventing any possible injuries during the use of the cleaver, the invention proposes that the crank according to the invention extends from the handle (4) in the direction of the cutting edge (11) along the blade and/or edge surface (5) on the handle side.

  • Publication number: 20080188164
    Abstract: The invention relates to a method for grinding a cutting tool, especially a knife. The aim of the invention is to provide a method which allows configuration of individual leaf or blade geometries at comparatively low costs. For this purpose, the cutting tool is contacted with the effective surface of a grinding device, and the cutting tool and the grinding device can be displaced in relation to each other by at least three degrees of freedom.

  • Publication number: 20060196877
    Abstract: The invention relates to a method for producing cookware (1) consisting of a base body (5) that is attached to a base (2), in particular a pot, pan or similar. In a first step of said method, the base body (5) is produced in one-piece, preferably in a deep-drawing process and in a second step, the base body (5) is connected to the preferably multi-part base (2), which is composed of an inlay (6) and a shell (7) that encapsulates said inlay (6). The aim of the invention is to provide a simple and cost-effective method for producing cookware (1) comprising a base (2) that only deforms within narrow tolerance limits, even when subjected to comparatively high thermal stress. To achieve this, the base (2) is calibrated by means of a displacement-controlled press, preferably a toggle press.

  • Patent number: 6612204
    Abstract: A method for manufacturing a blade of a cutting tool, in particular, a knife. In order to create a process with which influence is to be exerted in a targeted manner on the technological material properties of the blade and material chipping to be avoided, as well as permitting economical manufacturing, a process is carried out by treating a blade base material with a laser in a first process step along a curve contour determined by the final edge of the blade and, in a second process step, the edge of the blade is formed, in particular, cut to shape, along the curve contour determined by the final blade form inside the laser-treated area, or the blade base material is machined in a first process step by punching or trimming to form the final edge, subsequently the laser treatment is performed in a second process step on the narrow side forming the final edge and finally, in a third process step, the blade is formed, in particular, ground, inside the laser-treated area.
