Description

[Detailed Description of the Invention] The present invention relates to an instrument for easily sharpening the blade of a sword to any desired angle.

Traditionally, it was very difficult to sharpen the blade of a sword, and if an amateur sharpened it, it would not be possible to sharpen it to a desired angle, and the blade would become clam-like, resulting in poor cutting quality even when sharpened, so a sharpener would be required. It was customary for sharpeners to sharpen the blade by rubbing the blade back and forth at an arbitrary angle with their hands against the surface of a whetstone moistened with water. Sharpened by a high level of skill and concentration.

The present invention was devised to eliminate this drawback, and to explain it with a drawing, as shown in Figure 5, the blade fixing metal fitting B and the cutting edge holding metal fitting C are combined with the filler A, and the wing screws K and L are combined. This is a fixture fixed in place, and the reinforcement is explained using the perspective view of the reinforcement shown in Figure 1 of the drawing.

It is.

The combination of the blade sharpening tool will be explained with reference to drawings 1, 2, 3, 4, and 5. The guide surface 6 of the filler 2 fixed to one end of the filler A and the fixing hole 3.
, the guide frame 7 and fixing adjustment hole 8 of the blade fixing bracket B.
and fix the filler A and the blade fixing bracket B in the holes 3 and 8 with thumbscrews K. Next, the guide surface 6 of the reinforcement 4 fixed to one end of the reinforcement A and the fixing hole 5
Figure 5 shows an instrument in which the guide frame 13 and adjustment fixing hole 14 of the cut end stopper C are aligned, and the filler A and the cut end stopper C are fixed to the holes 5 and 14 with thumbscrews L. , is a front view of the blade sharpening tool.

To explain the function of each part, the filler A is a filler A that aligns the side surface 1 of the filler A and the surface 17 of the blade M with the grindstone surface at a constant angle. Braces 2, 4, guide surface 6, guide surface 7 adjustment fixing hole 8 of blade fixing bracket B, guide surface 13 adjustment fixing hole 1 of tip stopper C
4. Thumb screws K and L are parts for adjusting and fixing the angle of the blade M of the blade M, as shown in Fig. 6.
To explain with reference to the enlarged cross-sectional view 8 of A', the blade M
This is the part that adjusts the distance between the cutting edge 15 and the filler A.If you widen the distance, the angle of the blade M will become smaller, and if you narrow the distance, the angle of the blade M will increase.You can freely adjust this. This is the part that is adjusted and fixed. The blade fixing metal fitting B is a metal fitting B that fixes the blade M between the ridge part 18 and the skin part 16 of the blade M, D.
9 is a hole D for inserting the blade M, 9 is a guide surface 9 for moving the mover F in a fixed plane, and 1
0 is a bottom plate 10 fixed to the bottom of the blade fixing bracket B, H is a thumb screw H attached to the fixed bottom plate 10, and by rotating the thumb screw H, the movable element F is moved up and down. It is a thumbscrew H.
E is the ridge floor E for fixing the ridge 18 of the blade M in a fixed position, F is the movable element F that moves the guide surface 9, and the groove G of the movable element F is the ridge 15 of the blade M.
19 is the groove G into which the part is fitted, and 19 is the skin part 1 of the blade M.
7 is an enlarged cross-sectional view of the roller 6 shown in FIG.
To explain with an enlarged cross-sectional view, first loosen the thumbscrew H, insert the blade M into the blade insertion hole D,
As it is tightened, the movable element F is pushed upward, and at this time, the cutting edge 15 of the blade M fits into the groove G of the movable element F, and before the cutting edge 15 hits the bottom of the groove G. The corner 19 of the groove G is the base 1 on both sides of the blade M.
6 parts are fixed and the blade M is pushed up, so the ridge part 18 of the blade M fits into the ridge floor part E and the blade M is fixed to the fixing metal fitting B. The cutting edge stopper C is a metal fitting C having a hole I for receiving the ridge part 22 and the skin part 21 of the cutting edge of the blade M, and is similar to the cutting edge stopping fitting C shown in FIG.
To explain with a partially enlarged diagram, I is a hole I into which the tip of the blade M is inserted and secured, and the hole I is a cross-sectional view of the tip part H-HA' in the partially enlarged view of the tip of the blade M shown in Figure 10. The hole I is a little smaller than the one shown in Figure 11. J is a cutting edge floor J which fixes the cutting edge ridge part 22 in a fixed position, and 23 is a surface 23 on which the cutting edge skin part 21 is applied, which has an angle that aligns with the cutting edge skin part 21 shown in FIG. 11.
24 is a sliding groove 24 for preventing the cutting edge 15 of the cutting edge from hitting the metal fitting C when inserting the cutting edge of the blade M into the hole I. Align the ridge 22 of the tip of the cutting tip of the blade M with the ridge J of the hole I of the cutting tip stopper C, and insert the cutting tip of the blade M into the hole I. The ridge part 22 of the cut tip is applied to the surface 23 where the skin part 21
are aligned and fixed to the stopper C as shown in Figure 13. The fixed cutting edge 15 is a cutting edge stopper C which can be fixed by inserting the blade M into the hole I, which fits into the slot 24 of the hole I and does not damage the cutting edge 15.

The method of using this invention is explained with drawings.
Loosen the thumbscrew H of the blade fixing metal fitting B of the blade sharpening tool shown in Fig. 5, align the tip ridge 22 of the blade M with the ridge E of the blade insertion hole D of the metal fitting B, and insert the blade M. By aligning the cutting edge ridge 22 of the blade M with the ridge J of the hole I of the cutting edge fixing fitting C, inserting the cutting edge to fix the cutting edge part of the blade M, and tightening the thumbscrew H of the blade fixing fitting B. , the blade M is fixed to metal fittings B and C of the blade sharpening tool. As shown in Figure 6,
Next, the method of determining the angle of the blade 17 of the blade M to an arbitrary angle will be explained with reference to the enlarged cross-sectional views of FIG. 8 and FIG. Sharpening tool, thumbscrew K shown in Figure 6,
Loosen L, arbitrarily adjust the distance between the cutting edge 15 of the blade M and the filler A, decide on the angle, tighten the thumbscrews K and L, fix the metal fittings B and C to the filler A, and the preparation for sharpening is completed. The sharpening method will be explained with reference to Figure 14 of the drawing and an enlarged cross-sectional view of Figure 6 A-A'.
Align the blade surface 17 of the blade M with the water-soaked whetstone surface N, as shown in Figure 14, and then sharpen the left and right blade surfaces 17 while rubbing the blade M back and forth.When the sharpening is complete, the blade fixing bracket B Loosen the thumbscrew H, align the ridge 18 of the blade M with the ridge E of the metal fitting B, and pull out the blade M from the metal fitting B to finish. Next time, you will be able to sharpen the same blade angle without having to adjust the blade angle. Furthermore, when sharpening the blade at the base of the blade, attach blade fixing metal fittings to both ends of the sprocket and sharpen the blade while fixing it.

As for the effects of this invention, since the ridge and skin parts of the blade are fixed to the blade fixing bracket, the blade can be easily fixed without damaging the blade, and the blade can be fixed to the blade sharpening tool. When sharpening a blade, even an amateur can easily sharpen it to a certain angle at any angle, and the sharpness can be as sharp as that of a sharpener.
