PROBLEM TO BE SOLVED: To provide a quick back-type cutter knife that has shortened an overall length of a slider to reduce the size of a cutter body, and has improved operability.SOLUTION: A cutter knife 1 includes: a holder 3 for housing a cutter blade C; a main slide body 5 attached to the holder 3 so as to move backward and forward; a retaining mechanism 9 for retaining the main slide body in the holder 3; a secondary slide body 7 attached to the main slide body 5 so as to move backward and forward, to which the cutter blade is connected; and an elastic member 21 connected to the main slide body 5 and the secondary slide body 7 that energizes the secondary slide body 7 backward when the secondary slide body 7 is caused to move forward with respect to the main slide body 5. The main slide body 5 and the secondary slide body 7 are arranged so as to be vertically overlapped with each other. 【課題】スライダー全体の長さを縮小してカッター本体の小型化を可能にするとともに、操作性を向上させたクイックバック式のカッターナイフを提供する。【解決手段】本発明のカッターナイフ１は、カッター刃Ｃを収容するホルダー３と、ホルダー３に前後移動可能に取り付けられる主摺動体５と、ホルダー３に主摺動体を留置する留置機構９と、主摺動体５に前後移動可能に取り付けられるとともに、カッター刃Ｃを連結する副摺動体７と、主摺動体５および副摺動体７に連結されて、副摺動体７を主摺動体５に対して前動させた際に該副摺動体７を後方に付勢する弾性部材２１と、を備え、主摺動体５および副摺動体７が、上下方向に重なるよう配置されてなることを特徴とする。【選択図】図１
