Abstract

The knife has a blade with a cutting edge (4) and an opposite back (8). Both sides (6,7) of the blade between edge and back have continuous hollow-grinding. The grinding is mirror-symmetrical on either side of an axis (9) extending at right angles to the center of blade and back. It extends over the complete length of the blade, from tip to grip.

Description

Die Erfindung betrifft eine Messerklinge eines Messers zum Ausbeinen mit einer Schneide und einem der Schneide - quer zur Längsrichtung der Messerklinge gesehen - gegenüberliegenden Rücken.The invention relates to a knife blade of a knife for boning with a cutting edge and a cutting edge - transverse to the longitudinal direction of the Knife blade seen - opposite back.

Unter Ausbeinen ist das Lösen von Knochen aus dem Fleisch zu verstehen. Grundsätzlich kann man mit einem Messer schneiden, stechen oder schlagen. Kein Messer ist jedoch für alle Anwendungen gleich gut geeignetentsprechend gibt es Messer mit jeweils speziell besonders geeigneten Klingenformen. Unterscheiden lässt sich die Breite der Klinge, die Länge, eine gerade oder hochgebogene Klinge, eine glatte oder gesägte Schneidefläche und die Form der Spitze.Boning is the release of bone from the meat to understand. Basically you can cut, prick or stab with a knife beat. However, no knife is equally well suited for all applications There are knives with especially suitable ones Blade shapes. Distinguish the width of the blade, the length, a straight or upturned blade, a smooth or serrated blade Cutting surface and the shape of the tip.

Soll häufig sehr scharf und nicht tief geschnitten werden, kann ein Hohlschliff von Vorteil sein. Durch häufiges Ausbeinen, welches als eine harte körperliche Arbeit anzusehen ist, wird die Schneide der Messerklinge stumpf. Das Nachschleifen der Schneide ist je nach Klingenform aufwändig.Should often be very sharp and not deep cut, a can Hollow grinding should be an advantage. By frequent boning, which as one hard physical work, is the cutting edge of the knife blade dull. The regrinding of the cutting edge is complex depending on the blade shape.

Aufgabe der Erfindung ist es, ein Messer insbesondere zum Ausbeinen zu schaffen, das leicht handhabbar ist und dessen Schneide leicht nachgeschliffen werden kann.The object of the invention is to provide a knife in particular for boning create, which is easy to handle and the cutting edge easily can be reground.

Diese Aufgabe wird durch ein Messer mit einer Messerklinge der eingangs genannten Art gelöst, welche als weiteres Merkmal gemäß Patentanspruch 1 einen auf beiden gegenüberliegen Klingenseiten von der Schneide bis zumquer zur Längsrichtung der Messerklinge gesehen - gegenüberliegenden Rücken durchgehend ausgebildeten Hohlschliff aufweist. Die erfindungsgemäße Messerklinge ist insbesondere für Ausbeinmesser geeignet. Die Messerklinge kann aber auch bei Messern für andere Verwendungen eingesetzt werden. Fleischermesser oder Küchenmesser oder sonstige Messer mit der erfindungsgemäßen Messerklinge sind durchaus vorstellbar.This task is done by a knife with a knife blade of the beginning mentioned type, which as a further feature according to claim 1 one on both opposite sides of the blade from the edge to the cross seen to the longitudinal direction of the knife blade - opposite Back has continuously formed hollow ground. The knife blade according to the invention is particularly for boning knife suitable. The knife blade can also be used with knives for others Uses are used. Butcher knife or kitchen knife or other knives with the knife blade according to the invention are quite conceivable.

Aufgrund der durchgehenden Ausbildung des Hohlschliffs und der damit verbundenen Materialeinsparung gegenüber einem Messer ohne derartigen Hohlschliff besitzt das Messer mit der erfindungsgemäßen Messerklinge ein geringeres Gewicht.Due to the continuous formation of the hollow grinding and thus associated material savings compared to a knife without such Hollow has the knife with the knife blade according to the invention a lower weight.

Das Messer mit der erfindungsgemäßen Messerklinge ist leichter handhabbar, weil es eine dünne Messerklinge aufweist. Das Schneidgut wird dadurch nicht so stark auseinander gedrückt. Der Widerstand beim Schneiden ist reduziert. Das Schneidgut haftet nicht so stark an der Messerklinge. Der Schnitt ist leichter durchführbar. Vorteilhafterweise ist der quer zur Längsrichtung der Messerklinge verlaufende Hohlschliff über die gesamte Messerklinge in ihrer Längsrichtung vom Messergriff bis zur Messerspitze vorhanden. Die Messerklinge dringt leichter ins Schneidgut ein. Es wird im Vergleich zum Stand der Technik ein geringerer Kraftaufwand benötigt. Typische Berufskrankheiten des Fleischers wie Gelenkschmerzen können weniger häufig auftreten.The knife with the knife blade according to the invention is lighter manageable, because it has a thin knife blade. The cutting material is not so much pushed apart. The resistance at Cutting is reduced. The cutting material does not adhere so strongly to the Knife blade. The cut is easier to carry out. Advantageously, the Hollow cut extending transversely to the longitudinal direction of the knife blade entire knife blade in its longitudinal direction from the knife handle to the Knife tip available. The knife blade penetrates into the food more easily. It is compared to the prior art, a lower force needed. Typical occupational diseases of the butcher such as joint pain can occur less frequently.

Darüber hinaus kann die Schneide einer Messerklinge mit durchgehendem Hohlschliff leichter nachgeschärft werden. Das Nachschleifen kann durch einen entsprechenden Stein, eine Maschine etc. durchführt werden. Daraus kann eine höhere Akkordleistung beim Nachschärfen mittels Wetzstahl resultieren. Die erfindungsgemäße Messerklinge liegt beim Nachschärfen im Vergleich zu einer anders geformten bekannten Messerklinge besser an einer ebenen Schleiffläche an. Die Messerklinge wird beim Nachschärfen durch die verbesserte Anlage an einer Halterung (Magnet) weniger verkratzt.In addition, the cutting edge of a knife blade with continuous Hollow ground sharpened more easily. The regrinding can be done by a corresponding stone, a machine, etc. are performed. from that can a higher chord performance when re-sharpening by means of sharpening steel result. The knife blade according to the invention is located during re-sharpening in Compared to a different shaped known knife blade better a flat grinding surface. The knife blade becomes during sharpening less thanks to the improved attachment to a holder (magnet) scratched.

Durch die Wahl der bezüglich der Längsmittenebene der Messerklinge ausgebildeten Spiegelsymmetrie bzw. Asymmetrie des Hohlschliffs auf den beiden Klingenseiten wird eine Anpassung an unterschiedliche Arbeitsbedingungen erreicht. Diese schließen beispielsweise Benutzungen durch Links- oder Rechtshänder oder verschiedene Arten von Schneidgut ein.By the choice of the longitudinal center plane of the knife blade formed mirror symmetry or asymmetry of the hollow ground on the both blade sides will adapt to different Working conditions achieved. These include, for example, uses by left-handed or right-handed or different types of cutting material one.
