    • A utility blade (10) especially adapted for a roofing knife. The blade is fabricated from a flat, thin blank of metallic material and has a square central mounting hole (11) for mounting in a conventional roofing knife. A first end (16) of the blade (10) is configured with a curvilinear, sharpened hook (20b) on one side and a V-shaped sharpened cutting component (22a) on the other side. The V-shaped sharpened cutting component terminates into a sharpened point (22b). This arrangement is effective to give a user the advantage of having two different type cutting surfaces in one blade.
    • 特别适用于屋顶刀的实用刀片(10)。 刀片由平坦的薄金属材料制成,并具有用于安装在常规屋顶刀中的方形中心安装孔(11)。 叶片(10)的第一端(16)在一侧上形成有曲线形的尖锐的钩(20b),另一侧上形成有V形的切削刃(22a)。 V形锐化切割部件终止于锐化点(22b)。 这种布置对于给予使用者在一个叶片中具有两个不同类型的切割表面的优点是有效的。

    • The roofing tile cutting template (20) is a guide for cutting roof tiles (38) near a valley intersection of two roof sections. The template is for use with tiles having a contoured surface. The template shares the contour of a particular type tile so that the template conforms to the surface of the tile when laid on the tile. The template includes one or more slots (22a, 22b, 22c, 22d, 22e) cut through the surface of the template to provide guides for ruling a cutting line on the tile. The template is positioned on a tile so that the slot corresponding to the geometry of the particular roof intersection intersects a mark placed on the tile indicating one dimension of the final cut tile. The lot is then used to rule an accurate cutting line on the tile.
    • 屋顶瓦切割模板(20)是用于在两个屋顶部分的谷交叉点附近切割屋顶瓦(38)的引导件。 模板用于具有轮廓表面的瓷砖。 模板共享特定类型的瓦片的轮廓,以便模板在布置在瓦片上时符合瓦片的表面。 模板包括穿过模板表面切割的一个或多个槽(22a,22b,22c,22d,22e),以提供用于对瓦片上的切割线进行划线的引导件。 模板位于瓦片上,使得对应于特定屋顶交叉点的几何形状的狭槽与放置在瓦片上的标记相交,指示最终切割瓦片的一个维度。 然后,该批次用于对瓷砖上的精确切割线进行规则。

    • The roofing tile cutting template (20) is a guide for cutting roof tiles (38) near a valley intersection of two roof sections (30, 32).
