Abstract

PURPOSE: To provide a kitchen knife inexpensively by preventing a cutout piece from adhering to the side of a kitchen knife body at the time of shaping after a hardening process. CONSTITUTION: This kitchen knife has a handle 4 and a double-edged or single- edged kitchen knife body 1. The whole area of both or one side of the knife body 1 is subjected to an electric discharge machining process and finished to satin surface 3. As a result, the pieces of a cut material do not adhere, due to the roughness of the satin finished surface 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knife, and more particularly to a knife in which cut pieces of cut products such as cut vegetables and fresh foods are prevented from adhering to or adsorbing to the side surface of the knife body.

[0002]

2. Description of the Related Art In a kitchen knife, cut pieces of cut vegetables, fresh foods, etc. are often attached or adsorbed to the side surface of the knife body, which is very useful for cooks such as housewives. It had the drawback of being difficult to cook.

Therefore, conventionally, for example, as shown in FIG. 3, the knife body 21 is provided with a plurality of round holes 23 along the blade edge 22 at an appropriate position in the vicinity of the blade edge 22 portion thereof. The rounded holes 23 prevent the cut pieces of the cut pieces from adhering to or adsorbing to the side surface of the knife main body 21, so that the cut pieces can be cooked orderly without jumping out from the cutting board.

[0004]

However, when a circular hole 23 is opened in such a knife body 21, since the knife body 21 itself is a blade, the circular hole 23 is opened in the knife body before quenching. It becomes necessary to have a step of quenching after the holes have been drilled.

Therefore, there are problems that the process of opening the round hole 23 is troublesome, warpage occurs due to the existence of the round hole 23 during quenching, and quenching is not performed uniformly. was there.

In view of the above-mentioned problems and the like, the present invention prevents the cut pieces of the cut object from adhering to or adsorbing to the side surface of the knife body during molding after quenching to minimize the warpage of the knife body during quenching. It was created as a problem to provide a low cost knife that can suppress quenching evenly and uniformly.

[0007]

SUMMARY OF THE INVENTION The present invention has a handle and a double-edged or single-edged knife main body, and the entire surface of both sides or one side of the knife main body, or both sides of the knife main body including at least the vicinity of the blade edge or The problem described above is solved by forming a part of one surface on the matte surface by electric discharge machining.

[0008]

The knife according to the present invention has a handle and a double-edged or single-edged knife main body, and the entire surface of both sides or one side of the knife main body, or both sides or one side of the knife main body including at least the vicinity of the cutting edge portion. Since the part is formed on the matte surface by electrical discharge machining, it can be processed into metal after quenching itself, so it is a simple process of electrical discharge machining after quenching the knife body,
The entire surface of both sides or one side of the knife main body, or at least part of both sides or one side of the knife main body including the vicinity of the cutting edge portion has a fine uneven surface, and the pear surface has fine unevenness, so The presence of air in the recess prevents the cut pieces of the cut object from adhering or adsorbing to the side surface of the knife body.

[0009]

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

That is, reference numeral 1 shown in FIG. 1 is a knife main body, and the knife main body 1 is provided with a handle 4. The knife main body 1 is already hardened with one edge along the longitudinal direction as a single-edged or double-edged blade edge 2.

Then, on both sides of the knife body 1,
A textured surface 3 is formed by electric discharge machining. The matte surface 3 has fine irregularities having a roughness of, for example, about 0.05 to 0.1 mm, and this electric discharge machining is performed by an extremely common electric discharge machine (not shown).

In this case, if the cook is right-handed, the left side of the knife main body 1 or the left-hand side of the knife main body 1 is the side on which the cut piece of the cut object is not located. It is also possible to form the satin-finished surface 3 on only one side.

On the other hand, as another embodiment, as shown in FIG. 2, at least the cutting edge 1 of the knife body 11 with the handle 14 is attached.
A matt surface 13 having an appropriate width is formed along the cutting edge 12 in the vicinity of the two portions. Also in this case, this pear ground 1
3 is provided on both sides or one side of the knife main body 11.

Here, since the roughness of the fine concavities and convexities can be appropriately set by electric discharge machining, these matte surfaces 3, 13 can be set to the optimum ones, and the above-mentioned 0.05 to 0.1.
The roughness is not limited to mm. Further, although the invention has been described with respect to a knife, in addition to the knife, for example, if a knife is also described above and the matte surfaces 3 and 13 are formed, the cut pieces of the cut object are prevented from adhering or adsorbing to the side surface. It goes without saying that any kind of knife can be used as long as it is capable of cooking, let alone a knife of any kind.

[0015]

The present invention thus formed has the handles 4 and 14 and the double-edged or single-edged knife main bodies 1 and 11, and the entire surfaces of both sides or one side of the knife main bodies 1 and 11,
Alternatively, since both sides or part of one side of the knife main bodies 1 and 11 including at least the vicinity of the cutting edges 2 and 12 are formed on the matte surface 3 and 13 by electric discharge machining, the electric discharge machining itself can be processed into a metal after quenching. Therefore, with the simple processing of electrical discharge machining after quenching the knife body 1, 11, the knife body 1,
The entire surface of both sides of 11 or the entire surface of one side, or at least both sides of the knife main body 1, 11 including at least the vicinity of the blade edges 2 and 12 or a part of one side thereof can be a finely textured matte surface 3, 13 Since the portions 3 and 13 have minute irregularities, it is possible to prevent air from being present in the concave portions so that the cut pieces of the cut object are not attached or adsorbed to the side surfaces of the knife main bodies 1 and 11.

Therefore, it is possible to minimize warpage of the knife main body during quenching and to even out the quenching by preventing the cut pieces of the cut article from adhering or adsorbing to the side surface of the knife main body by extremely simple molding after quenching. Therefore, it has various excellent effects that it can be provided at low cost.
