    • A blade (10) for a utility knife is provided which has a trapezoidal shape with a cutting edge (12) and a pair of side edges (16) which converge towards a blunt back edge (14). A safety edge (28) joins each of the side edges (16) with the cutting edge (12). The safety edges (28) intersect with the cutting edge (12) at an obtuse angle and provide substantially blunt surfaces. Safety corners (24) are formed at intersections of the safety edges (28) and the side edges (16). The safety corners (24) are disposed at the outermost distal ends of the blade (10) relative to the cutting edge (12). Cutting corners (26) are formed at the intersections of the safety edges (28) and the cutting edge (12). The cutting corners (26) are disposed inwardly along the cutting edge (12) relative the safety corners (24). This way, inadvertent contact between an operator and a safety edge (28) would not be likely to cause injury since the safety corners (24) would be contacted first.
    • 提供一种用于实用刀的刀片(10),其具有梯形形状,具有切割边缘(12)和朝向平钝后缘(14)会聚的一对侧边缘(16)。 安全边缘(28)将每个侧边缘(16)与切削刃(12​​)连接。 安全边缘(28)以钝角与切割刃(12)相交并且提供基本上钝的表面。 安全角(24)形成在安全边缘(28)和侧边缘(16)的交点处。 安全角(24)相对于切削刃(12​​)设置在刀片(10)的最外侧的远端。 在安全边缘(28)和切削刃(12​​)的交点处形成切割角(26)。 切角(26)相对于安全角(24)沿切削刃(12​​)向内设置。 这样,由于安全角(24)将首先被接触,所以操作者与安全边缘(28)之间的无意接触将不会引起伤害。
