施し段部（Ｄ＋を形成していた。The conventional manufacturing method for leaking scissors is as shown in Figure 11.
A lower blade CAI that does not include the center part was made, and the weld line (Bl) was butt-welded to the handle (C1), and a part of the inner part (C) was built up to form a stepped part (D+). .
つまり段部は極軟鋼の肉盛りによって形成されるだめ、
長期間の使用によって段部か磨滅してしまいストッパー
の機能をはださなくなり、怪我をする危険性かあった。In other words, the stepped portion is formed by overlaying extremely mild steel.
After long-term use, the stepped part would wear out and the stopper would no longer function properly, posing a risk of injury.

にくい丈夫々握り鋏を作れるよう（でしたものである。In forming the upper blade (2) and the lower blade (3), the present invention includes shapes including the IYI' parts (2a) and (3a), respectively, which are joined to the handle (1), and the stepped part (4) is formed by forming a protrusion (7) protruding inward on the cutting edge side at the reach of the lower blade, crushing the protrusion by hammering in the width direction, and then by forging. By keeping the back side flush and making the blade side, which is made of knife steel, bulge by the amount of the 6fS mark protrusion, and using this to form a step with the knife steel, it is possible to make durable gripping scissors that are resistant to wear. This is what I did.
以下 本発明握り鋏の製造法の実施例を雄部の図面に基
ついて説明する。Hereinafter, an embodiment of the method for manufacturing gripping scissors of the present invention will be described with reference to drawings of the male part.
鋏の刃部（ｄ４輿：ｌ１１−鋼板の片面に細１〕の刃物
鋼（５）を一体重Ｋｆｆｉ着した複合月別を使用し、第
２図に示すように、鍵部を含む形状の」二刃と下刃とを
刃面とうし突き合せだ状態に利別取りする。The blade part of the scissors (D4 pallet: L11 - Thin 1 on one side of the steel plate) is made of a composite piece of knife steel (5) with a single weight Kffi attached, and as shown in Figure 2, it has a shape including the key part. The two blades and the lower blade are brought into contact with each other and the blades are pressed against each other.

柄（１）の両端にそれぞれ上刃（２）と下刃（３）とを
欠き合せ溶接する。In other words, make the blade body shape (6) for one pair of scissors, and make the third Igl.
The center of the knife steel (5) is heated to separate it into an upper blade (2) and a lower blade (3). At this time, lower blade (3
) has a protrusion (7
). Then, as shown in Figure 1, an upper blade (2) and a lower blade (3) are welded together at both ends of the rod-shaped handle (1), respectively.

軟鋼の上部表面を覆う形で分布するようになる。Next, as shown in Fig. 5, the protrusion (7) of the first part (3a) is cut by cutting in the width direction by hot forging, and the protrusion (7) is removed. ) becomes thicker and bulges out on both surfaces as shown in Figure 6, and is distributed in such a way that it covers the upper surface of the mild steel.
その後 極軟鏑面、つ甘り刃部の裏側か面一となるよう
（てし、突部（７）による肉厚の増加分を力面側に膨出

最終的に第１〕図に示すように、柄（１）を偏平とし、
焼き入ノ１、刃部け、磨きなとの仕上げ加工を施し、柄
の中心部で約１８０度Ｕ字状に折曲し握り鋏を完成する
。After that, the extra soft side of the blade is flush with the back side of the curved blade part (the increased wall thickness due to the protrusion (7) is bulged out to the force side, and this is used for No. 1j). Form a step (4). (
(Fig. 7, Fig. 8) Finally, as shown in Fig. 1, the handle (1) is flattened,
After finishing the work by hardening, sharpening the blade, and polishing, the handle is bent approximately 180 degrees into a U-shape at the center to complete the gripping scissors.
なお、突部（７）を形成する首部（３ａ）には第１０図
に示すように極軟鋼の面に肉盛りを施しておけば、段部
を形成するに当り便利てあり、寸た突部を可及的に小さ
なものとすることかてきる。In addition, it is convenient to form a stepped part if the neck part (3a) forming the protruding part (7) is built up on the surface of the very mild steel as shown in FIG. It is possible to make the section as small as possible.
水元明如よれば、下刃の首部（マチ）に形成する段部、

に段部力・摩滅し、ストッパーの役目をはださなくなる
ようなことのない握り鋏を製することかてきる。According to Mizumoto Akinyo, the step formed at the neck (gusset) of the lower blade,
The neck surface of the upper blade that comes into contact with the stepped part is made of the same blade steel as the blade part, and the blade steel can be distributed more widely by splitting it on the side of the stepped part. It is possible to make gripping scissors that will not wear out or become ineffective as a stopper.
