    • A device for cutting paper or other materials is provided. This device includes a substantially flat base, wherein the base is adapted to receive paper and other flat material for cutting. A manually-operated cutting blade assembly is pivotally attached to either the right or left side of the base. The cutting blade assembly includes an elongated cutting arm positioned over a predetermined line of cut on the base. A sighting device is mounted on the base on the same side as the elongated cutting arm and further includes a housing and an adjustable light source mounted within and protected by the housing. The light source projects a fixed line of visible light along the predetermined line of cut. A switch is included for activating and deactivating the light source. A first portion of the switch is located in the handle grip and a second portion of the switch is located within the housing. The light source is activated when the elongated cutting arm is raised and is deactivated when the elongated cutting arm is lowered.
    • 提供了用于切割纸或其它材料的装置。 该装置包括基本上平坦的基部,其中基部适于接收用于切割的纸和其它平坦材料。 手动操作的切割刀片组件可枢转地附接到基座的右侧或左侧。 切割刀片组件包括定位在基座上的预定切割线上的细长切割臂。 瞄准装置安装在与细长切割臂相同的一侧的基座上,并且还包括安装在壳体内并由壳体保护的壳体和可调光源。 光源沿预定的切割线投射固定的可见光线。 包括用于启动和停用光源的开关。 开关的第一部分位于手柄中,并且开关的第二部分位于壳体内。 当细长切割臂升高时,光源被激活,并且当细长的切割臂下降时,光源被停用。
