PURPOSE: A curved cutter knife is provided to prevent damage to an object by giving proper pressure to a cut face. CONSTITUTION: A curved cutter knife comprises a blade main body(1), a sheath(2), a slider(3), a stopper(4), and a handle. A blade(11) is formed on the bottom part of the blade main body. The top part of the blade and blade main body has continuous curvature with a fixed width. The blade moves along the guide passage of the sheath. The slider gradually slides the blade along the guide passage. The slider is located at the tip-end part of the sheath and connects the blade main body and sheath. The stopper blocks up the backend of sheath. The handle is projected to the guideline of the sheath. If a user moves a handle to the tip-end part of the sheath, the tip-end part of sheath, the slider, and the blade main body are closely contacted in order to prevent the movement of the blade main body. |
