Description

[Detailed Description of the Invention] The present invention relates to an instrument for sharpening the blade of a cutlery, and aims to provide a tool that can be operated safely and that can easily form a sharp blade.

That is, as shown in FIGS. 1 and 2, the knife sharpener according to the present invention is a grindstone that has an insertion hole 1 at its tip and has a fixing screw 2 screwed onto its upper part so as to protrude into the insertion hole. A shaft 4 that freely slides through the holder 3 is installed between a pair of supports A6 protruding from the base plate 5, and a bent edge 9 that hangs down at both ends of the tool base plate 8 to which a magnet 7 is attached. A pair of supports B protrude from the base plate 5 through which system locking screws 10 are freely rotatable.
11, the tool base plate 8 is constructed between the supports 811 so as to face the shaft 4 obliquely.

In this way, the grindstone 12 is inserted into the insertion hole 1, fixed by pressure with the fixing screw 2, and then the cutter 14 is inserted while the blade 13 is facing the direction of the axis 4 as shown in FIG. After adsorbing and fixing the base plate 8 to the magnet 7, if the grindstone holder 3 is slid along the shaft 4 while bringing the grindstone 12 into contact with the blade 13,
A blade 13 can be safely polished without touching the blade 14.

The reason why the tool base plate 8 is positioned obliquely to the shaft 4, that is, to the polishing direction of the whetstone 12, is because the polishing direction of the whetstone 12 must be diagonally crossed to the tip line of the blade 13. This is because the tip of the blade 13 is not completely sharp.

In addition, the so-called sharp blade 13 does not have a straight, acute-angled cross section, but has a candy-like curved side line; this is because the cut surface of the cut object is straight. This is because the phenomenon of adsorption to the surface of the blade 13 tends to occur, and the movement of the blade 13 is inhibited.

In the knife sharpener according to the present invention, the knife base plate 8 can be fixed to the support column Bit or can be rotated by adjusting the tightening degree of the locking screw 10, and the grinding wheel holder 3
Since the blade can be rotated around the shaft 4, the tool base plate 8 can be rotated as shown in FIG. The candy-like blade 13 can be shaped easily and quickly.

Incidentally, the direction of rotation of the tool base plate 8 when forming the candy-like blade 13 is opposite to the direction shown in FIG. 4 when the pillar A6 is shortened and the position of the grindstone holder 3 is lowered.
