2. Description of the Related Art There is a blade sharpener having a structure in which a pair of grinding wheels having a disk shape are arranged such that their rotation center axes form a predetermined angle. In this blade sharpener, the grindstones are arranged so as to have a front rake angle and a side rake angle with respect to the blade pulling direction, so that the blade does not bite into the blade.

を厳密に寸法管理しながら刃物研ぎ器を組み付ける必要
があり、組付けコストがかさむ。In the case of the former blade sharpener, since the grindstone has a disk shape, the sharpening is performed at the edge of the grindstone when sharpening the cutting edge. By grinding at the edge, the edge is sharpened rather than polished. Therefore, for example, when sharpening a knife made of a relatively hard material such as chromium-molybdenum steel, the cutting edge may be shaved and the cutting edge may be partially chipped. In addition, since the blade edge is sharpened at the edge of the grindstone, it is necessary to assemble the blade sharpener while strictly controlling the front rake angle and the side rake angle, which increases the assembly cost.

It is necessary to prepare in advance a combination of dedicated grindstones for various types of sharpeners, such as a grinder for sharpening, a sharpener for sharpening, etc., which poses a problem in inventory management. Further, even if only one side of the grindstone is worn, each pair of grindstones must be replaced, resulting in waste.

As shown in FIGS. 2 and 3, each of the grindstones 35 and 36 has a configuration in which a circular stainless steel plate is pressed into a frustoconical shape in a side view. More specifically,
As shown in FIG. 3, the grindstones 35 and 36 are dish-shaped main bodies 35a and 36 having shaft insertion holes 35h and 36h at the bottom center.

In addition, the grinding stones 35 and 36 are for roughing.
About 500 diamond abrasive grains are used. In the shaft insertion holes 35h and 36h of the grinding stone, the protruding edge 25 is provided at one end.
The other ends of the shafts 25 and 26 on which the shafts a and 26a are formed are inserted so that the grindstones 35 and 36 and the shafts 25 and 26 are not separated by caulking. The shafts 25 and 2
The material of No. 6 is stainless steel.

Each of the supports 15 and 16 is a plastic block having a substantially rectangular parallelepiped shape, and a U-shaped notch for shaft insertion / holding in a side view is formed on an upper surface of each of the supports 15 and 16. A latch engaging projection (not shown) is formed at the upper end of the notch so that the shafts 25 and 26 can be firmly fitted into the notch.

角α＝６０度（β＝６０度）である。The grindstones 35 and 36 are detachably attached to the base 11 via the supports 15 and 16 at positions such that the cutting edges of the knife to be sharpened are alternately sandwiched. That is, each of the grindstones 35 and 36 can be removed from the supports 15 and 16, and the grindstones 35 and 36 can be removed from the supports 15 and 1, respectively.
6 together with the base 11. The grinding wheels 35 and 36 are arranged such that their rotation center axes form a predetermined angle (α + β when viewed from above). Specifically, in the present embodiment, the angle α = 60 degrees (β = 60 degrees) formed by the top view of the contact direction of the blade and the central axis of the grindstone 35 (36).

The closest peripheral edges 35b and 36b are located on a straight line that indicates the direction in which the blade is pulled from above.
Accordingly, as shown in FIG. 4, the grindstones 35 and 36 come into contact with the cutting edge in the regions K and L on the downstream side (the handle side of the kitchen knife) and slightly above the rotation center axis with respect to the pulling direction of the kitchen knife. The kitchen knives are sharpened in the leverage areas K and L.
As described above, since the contact areas K and L of the respective grinding stones with respect to the kitchen knife are separated by a certain distance in the direction in which the blade is applied,
The knife can be reliably pulled along the pulling direction, and the blade edge can be sharpened uniformly.

Instead of attaching each support at an angle of α + β), another support having a dimension and shape capable of making a small angle change may be attached. This makes it possible to cope with various methods of sharpening, such as when sharpening a single-edged knife, or when performing special cutting or cutting of a knife.

い。The knife sharpener 10 is constructed as described above. The rough sharpening is performed by inserting the blade edge of the knife into the slit 12s of the rough cutting portion shown in FIG. 1 and pulling the knife in the pulling direction indicated by the arrow. Finishing sharpening is performed by rotating the blade sharpener 10 by 180 degrees, inserting a cutting edge into the slit 13s of the finishing portion, and pulling the kitchen knife in the direction of the arrow. In the case of the blade sharpener 10 according to the present embodiment, the grindstone has a frusto-conical shape, and the sharpened portion is formed on the peripheral edge thereof. The edge is not sharpened. Therefore, even when sharpening a knife made of a relatively hard material such as chromium-molybdenum steel, the cutting edge does not chip.

It is possible to quickly cope with various uses such as when it is desired to perform cutting or when performing cutting. Furthermore, only the worn whetstone can be replaced, and it can be used over a long period at low cost.

Since the blade sharpener according to the second embodiment has substantially the same configuration as the blade sharpener according to the first embodiment, FIG. 1 to FIG. 4 used in the description of the first embodiment will be omitted. It will be described based on the following. Knife sharpener 4
0, the same base as the blade sharpener 10 of the first embodiment,
Although a support is used, diamond abrasive grains are not adhered to one of the pair of rough grinding wheels 46 (see FIG. 1), and a roll portion is formed simply for receiving a blade edge. The diamond grinder is not attached to one side 48 of the pair of finishing whetstones, and a roll portion is formed simply for receiving a blade tip. Therefore, the configuration is the same as that of the blade sharpener 10 of the first embodiment. Make a difference.

It can be sharpened without chipping. Further, similarly to the first embodiment, it is possible to quickly cope with various uses such as a case where a user wants to perform a blade cutting of a single-edged knife and a case where a user wants to perform a blade cutting. Note that, unlike the above-described embodiment, as shown in FIG. 5, the sharpening portion of the grindstone may use grindstones 55 and 56 that form a fixed angle γ with respect to the direction in which the blade is pressed.

ても良い。As an example, a grindstone having a γ that sharpens the blade lowering portion is used for a grindstone for rough sharpening, and a grindstone having a slightly looser angle at the blade tip portion is used as a finishing grindstone. It is conceivable to use the knife to keep the sharpness of the kitchen knife long. Also, instead of forming the frusto-conical whetstone by press working, it may be made by cutting out stainless steel or the like, or by sintering alumina.

Further, a double-edged sharpening portion may be provided on one side of the base and a single-edged sharpening portion may be provided on the other side, or a sharpened portion may be provided on only one side of the base.
