    • A tool for aiding marking or cutting is described. A V-shaped member having an edge formed at an exterior apex of the V for guiding a marker or cutting tool. The exterior surfaces of the V-shaped member may have a material applied having a higher coefficient of friction than that of the V-shaped member. The edge at the apex of the V may have two substantially planar surfaces, each of which forms a complimentary angle with the interior apex angle of the V, or a thin metal portion formed in the exterior apex of the V so that an edge thereof protrudes sloping towards a surface on which the tool is laid. A graduated scale may be applied to an exterior surface of the tool at a location near the apex.
    • 描述了用于辅助标记或切割的工具。 V形构件,其具有形成在V的外部顶点处的边缘,用于引导标记或切割工具。 V形构件的外表面可以具有施加的摩擦系数高于V形构件的材料。 V顶点处的边缘可以具有两个基本平坦的表面,每个表面与V的内顶角形成互补角,或者形成在V的外顶点中的薄金属部分,使得其边缘突出 向工具放置的表面倾斜。 刻度尺可以在靠近顶点的位置施加到工具的外表面上。
