Disclosed is an edge for a tool and/or for an insert to be removably and/or fixedly mountable on a tool. The edge is formed at a meeting of a first surface and a second surface comprises at least one segment extending from a first peak to a second peak through a nadir interposed therebetween. The first peak has a first peak line passing therethrough, the second peak having a second peak line passing therethrough, and the nadir having a nadir line passing there-through. The first peak line, the second peak line, and the nadir line are parallel to each other, and a first depth D1 between the nadir line and the first peak line is greater than a second depth D2 between the nadir line and the second peak line.
