PROBLEM TO BE SOLVED: To provide a mowing sickle making a substitute edge unnecessary and capable of sufficiently whetting a sickle blade by only reciprocating the sickle blade on a grinding stone slightly 2-5 times.SOLUTION: In the mowing sickle, a blade body (a) has fitting holes 6 at a part on the right side and at a part on the right side from a blade tip sharpening part 2 and the thickness of the blade body is ultrathin and the blade body is made of a steel plate and rigid chromium plating is applied to whole face of the blade body (a) and a reinforcing body (b) is formed into a shape smaller than that of the blade body (a) and the reinforcing body (b) having a fitting hole 8 which is made to coincide with fitting hole 6 of the blade body (a) in the part of on the right side from the sharpening leading end part 7 and in the part on the right side is made of a steel plate material which is thicker than thickness of the blade body (a) and chromium plating treatment is applied to the whole face of the reinforcing body (b) and the reinforcing body (b) is superposed on a surface part 1 or a rear part 4 of the blade body (a) and fitting holes 6 and 8 of a blade body (a) and the reinforcing body (b) obtained by making a fitting hole 6 of the blade body (a) coincide with a fitting hole 8 of the reinforcing body (b) are made to coincide with a fitting hole 10 formed on a shank (d) and a fixing tool 12 is inserted into fitting holes 6, 8 and 10 and pressed and bonded and the lower part of the shank is inserted into a grip (c).COPYRIGHT: (C)2009,JPO&INPIT【課題】替刃を不要とし、砥石に僅か2~5回位往復運動をさせるだけで、十分に研ぎ上げることができるようにする。【解決手段】刃体aは、右側方部の部位と刃先尖状部2から右側方部の部位に夫々嵌挿孔6を有し、厚さが極薄の鋼板材製にして、刃体aの全面に硬質クロームメッキ処理を施し、補強体bは刃体aより小形状にして、右側方部の部位と尖状先端部7から右側方部の部位に刃体aの嵌挿孔6と合致する嵌挿孔8を有する厚さが刃体aの厚さよりも厚い鋼板材製とし、全面にクロームメッキ処理を施す。刃体aの表面部1や裏面部4に補強体bを重合し、刃体aと補強体bの嵌挿孔6、8を合致し、一体となった刃体aと補強体bの嵌挿孔6、8とシャンクdに形成の嵌挿孔10とを合致させ、その各嵌挿孔6、8、10に固定具12を挿入し圧潰接着してシャンクの下方部を握り柄cに刺し込む。【選択図】 図1
