Blades, blade structure, and method for manufacturing blades

Abstract

To provide a cutter, a cutter structure, and a manufacturing method of the cutter, that can restrict damage to a blade body regardless of the material quality, and retain the blade body at a handle part.SOLUTION: In a cutter 1, a core 12 of a blade body 10 is attached to a handle part 30 via a resin mouthpiece 20. The blade body 10 has a notch part 13 formed on the circumference of the core 12. The resin mouthpiece 20 includes: a columnar main body part 21; a slit 22 which is formed in the main body part 21, and to which the core 12 is inserted; an open hole 23 penetrating the main body part 21 so as to pass the notch part 13 in a state that the core 12 is inserted to the slit 22; and a connection pin 24 inserted to the open hole 23.SELECTED DRAWING: Figure 2

Claims

1. This is a bladed weapon in which the tang of the blade is attached to the handle via a resin ferrule. The blade body, The core has a notch formed on its periphery, The aforementioned resin nozzle is A columnar main body, A slit formed in the main body into which the core is inserted, With the core inserted into the slit, a through hole penetrates the main body portion so as to pass through the notch, The connecting pin inserted into the through hole, The first hole, which is a blind hole opening on the outer surface of the main body, A locking pin is inserted into the first hole and has a length shorter than the depth of the first hole, A lock spring is provided between the lock pin and the bottom of the first hole, and biases the lock pin in a direction that causes it to protrude from the first hole. It has, The aforementioned handle portion is The groove-shaped insertion portion into which the main body of the resin nozzle is inserted, A second hole, which is a blind hole, is formed on the inner surface of the insertion portion at a location that coincides with the first hole, and has a depth shorter than the length of the lock pin. It has, The lock pin, which is biased by the lock spring, is inserted so as to straddle both the first hole and the second hole. A bladed weapon characterized by the following features.

2. The blade body, The core has at least one second notch formed on its periphery. The blade according to feature 1.

3. The blade structure is such that the tang of the blade is attached to the handle via a resin ferrule. The blade body, The core has a notch formed on its periphery, The aforementioned resin nozzle is A columnar main body, A slit formed in the main body into which the core is inserted, With the core inserted into the slit, a through hole penetrates the main body portion so as to pass through the notch, A connecting pin inserted into the through hole and passing through the inside of the notch, The first hole, which is a blind hole opening on the outer surface of the main body, A locking pin is inserted into the first hole and has a length shorter than the depth of the first hole, A lock spring is provided between the lock pin and the bottom of the first hole, and biases the lock pin in a direction that causes it to protrude from the first hole. It has, The aforementioned handle portion is The groove-shaped insertion portion into which the main body of the resin nozzle is inserted, A second hole, which is a blind hole, is formed on the inner surface of the insertion portion at a location that coincides with the first hole, and has a depth shorter than the length of the lock pin. It has, The lock pin, which is biased by the lock spring, is inserted so as to straddle both the first hole and the second hole. A blade structure characterized by the following features.

4. A method for manufacturing a blade in which the tang of the blade is attached to the handle via a resin ferrule, The blade body, The core has a notch formed on its periphery, The aforementioned resin nozzle is A columnar main body, The main body has a slit into which the core is inserted, With the core inserted into the slit, a through hole is provided that penetrates the main body portion so as to pass through the notch, A connecting pin is inserted into the through hole, The first hole, which is a blind hole opening on the outer surface of the main body, A locking pin is inserted into the first hole and has a length shorter than the depth of the first hole, A lock spring is provided between the lock pin and the bottom of the first hole, and biases the lock pin in a direction that causes it to protrude from the first hole. It has, The aforementioned handle portion is The groove-shaped insertion portion into which the main body of the resin nozzle is inserted, A second hole, which is a blind hole, is formed on the inner surface of the insertion portion at a location that coincides with the first hole, and has a depth shorter than the length of the lock pin. It has, The core is inserted into the slit so that the notch and the through hole are aligned, and the connecting pin is inserted into the notch and the through hole to fix the blade to the resin ferrule. Furthermore, with the lock pin retracted into the first hole against the biasing force of the lock spring, the main body of the resin ferrule is inserted into the insertion part, and the main body is slid until the first hole and the second hole are aligned, thereby causing a part of the lock pin to protrude from the first hole due to the biasing force of the lock spring and be inserted into the second hole, thereby fixing the resin ferrule to the handle. A method for manufacturing blades, characterized by the following:
