  Such sharpeners are relatively expensive and have a problem that they cannot be sharpened in conformity with an inclined blade surface.

  Accordingly, an object of the present invention is to obtain an inexpensive blade sharpening tool that can be sharpened in conformity with an inclined blade surface.

  In order to achieve this object, a sharpening tool according to the present invention is provided in the vicinity of one end edge of a side face of the main body facing the blade of the main body, the blade angle guide capable of contacting the side face of the sharpening tool, and the main body. A sandpaper that can be detachably adhered to the main body so as to extend from the edge opposite to the edge side on which the blade angle guide is provided, to the position of the blade angle guide on the side facing the blade of the blade, A blade edge pointer provided on the main body and a grip for easily holding the main body are provided.

  According to the present invention, by aligning the blade edge pointer with the blade edge and making the blade angle guide lightly contact the side of the blade, the point of the sandpaper where the blade edge of the blade contacts and the point of the blade angle guide where the side of the blade contacts Since the line connecting the two lines matches the inclination angle of the blade, it can be sharpened in conformity with the inclined blade surface. Further, the main body can be made of a plastic with a simple structure, and the polishing surface is not an expensive ceramic, but an inexpensive sandpaper is used in an exchangeable manner, which is economical.

  In a preferred embodiment of the present invention, the main body is a flat block, the blade angle guide and sandpaper are provided on the bottom surface of the flat block, and the grip is constituted by a protrusion provided on the top surface of the flat block, The cutting edge pointer is provided on at least one of the top surface and the side surface of the flat block.

  Preferably, the blade edge pointer is a concave or convex portion or a colored marker.

  In another embodiment of the present invention, the main body is a rectangular block having a square cross section, and the blade angle guide and the sand are provided on at least one of the four side surfaces continuous in the circumferential direction of the square. Paper is provided, and grips as recesses that make it easy to grasp the rectangular blocks and the blade edge pointers are provided on axial side surfaces facing each other.

  Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a blade sharpening tool 1 according to a first embodiment of the present invention. A blade angle guide 3 capable of contacting the side surface of the blade is provided in the vicinity of one edge of the side surface of the main body 2 of the blade sharpening tool 1 that faces the blade to be sharpened. The sandpaper 4 can be detachably attached to the main body 2 so as to extend from the edge opposite to the edge side on which the blade angle guide 3 is provided to the position of the blade angle guide 3 on the same side as the blade angle guide 3 is provided. Provided. The side opposite to the polishing surface of the sandpaper 4 is an adhesive surface and is initially covered with release paper. The release paper is peeled to expose the adhesive surface, and the sandpaper 4 is attached to the side surface of the main body 2.

  A blade edge pointer 5 is provided on the side surface of the main body 2 different from the side surface on which the blade angle guide 3 and the sandpaper 4 are provided. The main body 2 is provided with a grip 6 that makes it easy to grasp the main body 2.

  In the embodiment shown in FIG. 1, the main body 2 is a flat block, the blade angle guide 3 and the sandpaper 4 are provided on the bottom surface of the flat block, and the grip 6 is constituted by a protrusion provided on the top surface of the flat block. The protrusion can be a grip having an opening therethrough or can be a protrusion with a recess recessed from both sides without penetrating.

  In addition, the blade edge pointer 5 can be a concave or convex portion or a colored marker provided on at least one of the top surface and the side surface of the flat block, but in the embodiment shown in FIG. The blade edge pointer 5 was constituted by the recess.

  As shown in FIG. 1 (c), the blade edge pointer 5 is operated on the cutting edge of the blade 7 placed on a table or a flat table and held by one hand, and the blade edge of the sharpening tool 1 held in the other hand. The pointer 5 is used as a guideline for polishing by sliding the sharpening tool 1 along the cutting edge. At this time, the sandpaper 4 is aligned with the inclination angle of the blade edge by the blade angle guide 3 contacting the position of the blade edge pointer 5 and the blade side surface 8 and can be sharpened in conformity with the inclined blade surface 9. At the position of the blade angle guide 3 in contact with the blade side surface, a gap is formed with respect to the blade side surface 8, and the sandpaper 4 comes into surface contact with the inclined blade surface 9 as a whole.

  It is economical if the width of the sandpaper 4 is slightly larger than the width of the inclined blade surface 9 so as to cover the entire inclined blade surface 9.

  FIG. 2 shows a blade sharpening tool 11 according to a second embodiment of the present invention. In the second embodiment, the main body 12 is a rectangular block having a square cross section, and the blade angle guide 13 and the sandpaper 14 are provided on at least one of the four side surfaces continuous in the circumferential direction of the square. The edge pointer 15 and the grip 16 as a recess for facilitating grasping the rectangular block are provided on the side surfaces in the axial direction facing each other. In the illustrated embodiment, the blade angle guide 13 and the sandpaper 14 are provided on two of the four side surfaces, respectively, but on one side, three side surfaces, or all four side surfaces. Each may be provided.

  The present invention can be used as a simple and inexpensive sharpening tool for sharpening knives used in general households.

The knife sharpening tool which is 1st Example of this invention is shown, (a) is a side view, (b) is a side view from the other side, (c) is a side view which shows a use condition. The knife sharpening tool which is 2nd Example of this invention is shown, (a) is a side view, (b) is a perspective view.
