Abstract
Description
【発明の詳細な説明】
在来、一般に使用されているのみ刃は軟鋼板と超鋼板（
通称ハイスと云う）とを一体に張り合わせた複合材を使
用している。[Detailed description of the invention] Traditionally, commonly used chisel blades are made of mild steel plate and super steel plate (
A composite material is used, which is made by laminating the steel (commonly known as high speed steel) together.
のみの使用に当たっては、ハンマーで叩いて使用したり
、切り込み部をこじ開けたりする等無理な使い方をする
ため、刃板が曲がってしまったり、また刃の砥ぎ出しを
行う時ζ二、軟鋼板を砥ぎ過ぎて刃先を鋭角にするため
、刃先がカミソリ刃のようになり、欠けたりする欠点が
あった。When using a chisel, the blade plate may bend due to excessive use such as hitting it with a hammer or prying open the notch, and when sharpening the blade. Because the blade is sharpened too much to make the edge of the blade a sharp angle, the edge becomes like a razor blade and has the disadvantage of being prone to chipping.
本発明は、かかる欠点を解決したのみ刃の製造法に関す

Similarly, it is formed into a handle rod (4) having a predetermined shape and having an insertion portion (7).

本発明は上述の様に構成したから次の様な特長を有する
ものである。Since the present invention is constructed as described above, it has the following features.
ｌ 刃板（６）はオール超硬鋼板であるから乱棒に扱っ
ても、長期使用しても曲がったりすることがなく、その
上、切れ味も良好で、耐久的に使用することが出来る。l Since the blade plate (6) is entirely made of cemented carbide steel plate, it will not bend even if it is handled roughly or used for a long period of time, and has good sharpness and can be used for a long time.
２ 仮りに刃（８）が摩耗して切れなくなっても砥ぎ出
しすることにより再び良く切れるのみになるＯ
この場合も、必要以上の砥ぎ過ぎがないから在来のよう
なカミソリ刃にならず、欠けるような心配がない。2. Even if the blade (8) becomes worn out and cannot be cut anymore, it can only be sharpened again by sharpening it. In this case as well, there is no need to oversharpen it, so it will not cut as easily as a conventional razor blade. No need to worry about it chipping.
３ また、使用に当たっても、ノＸンマーで叩く部分即

i;#(31keke□5, 1) This annealed copper material (2) part is formed into an unfinished handle rod (5) in a state similar to the specified shape of the handle rod (4) by rough machining. Then, in this state, forge the handle rod (4) into a predetermined shape.
Similarly, since the blade plate (6) of a predetermined shape is formed, the handle rod (4
