摘要： A method of making a cutting tool comprises providing a lever with a jaw having a cutting edge and a body arranged such that the cutting edge is offset from the body; providing a rotary cutting tool with an edge profile that may be complex and/or non-planar to form a complementary edge profile geometry on the cutting edge by moving the edge profile geometry of the rotary cutting tool along the length of the cutting edge.

摘要： A cutting tool and method comprises a first lever having a first jaw at one end. A second lever is connected to the first lever at a first pivot where the second lever has a second jaw that is opposed to the first jaw. A third lever is connected to the first lever at a second pivot and connected to the second lever at a third pivot such that relative movement of the third lever relative to the first lever between an open position and a closed position defines a stroke of the tool that corresponds to movement of the hand contact points on the levers toward one another. The third pivot comprises a pin engaging a cam surface where the cam surface has a shape such that the mechanical advantage may increase and decrease through the stroke of the tool and may be variable through the stroke of the jaws.

摘要： A cutting tool comprises a first cutting edge and a second cutting edge where the cutting edges are movable into engagement with one another. At least one of the cutting edges comprises an edge tip extending along at least a portion of the cutting edge. The edge tip has a curved outer surface that in cross-section is bounded by a first line defined by the equation y=74x2 where x is within the range −0.023 inches≦x≦0.023 inches and a second line defined by the equation y=294x2 where x is within the range −0.012 inches≦x≦0.012 inches. The outer surface may also be within a range defined by predetermined coordinates.
摘要翻译：切割工具包括第一切割边缘和第二切割边缘，其中切割边缘可以彼此接合。切削刃中的至少一个包括沿切削刃的至少一部分延伸的边缘末端。边缘尖端具有弯曲的外表面，其横截面由由等式y = 74x2限定的第一线限定，其中x在-0.023英寸＆lt; lE; x＆amp; nlE; 0.023英寸的范围内，并且由等式y = 294x2，其中x在-0.012英寸＆lt; llE; x＆amp; nlE; 0.012英寸的范围内。外表面也可以在由预定坐标限定的范围内。

摘要： A cutting tool comprises a first cutting edge and a second cutting edge movable into engagement with one another. The first cutting edge comprises an edge tip extending along at least a portion of the cutting edge. The edge tip has a geometry that lowers the cutting force required to cut hard articles and minimizes damage to the cutting edge. The edge tip has a flat end face defining a first edge and a second edge. A first side face extends from the first edge and a second side face extends from the second edge where the first side face and the second side face extend at an angle relative to one another such that the first side face and the second side face diverge as they extend away from the flat end face.
