Abstract

PURPOSE:To improve scissors into a structure requiring no rotation of both holding parts by rotatably supporting sheath members by both holding parts, forming finger rings between both sheath members and both holding parts, and receiving both cutting edge parts between both sheath members. CONSTITUTION:Plastic sheath members 8 having flexibility by a number of notches 8b are rotatably supported to holding parts 7 by mutually engaging the engaging protruding parts 9a and engaging holes 9b on their base end parts 9 and the engaging recessed parts 7a and engaging protruding parts 7b of the holding parts 7. When the top end parts 10 of the sheath members 8 are released from the holding parts 7 in the use state, the sheath members 8 are returned to cutting edge parts 4 side by their elasticity. When the engaging protruding part 10b on the top end part 10 of one sheath member 8 is engaged with the engaging recessed part 10c of the top end part 10 of the other sheath member 8, the both cutting edge parts 4 can be received between the both sheath members 8. When the engagement between the top end parts 10 of the both sheath members 8 is released in the non-use state, and the both sheath members 8 are bent to the both holding parts 7, the use state is formed. As the holding parts are integrally fixed to metal plate parts 6 extended from the both cutting edge parts 4, the both holding parts 7 are never loose when used.
