Sharpening these implements can be expressed as the creation of two intersecting planes which produce an edge that is sharp enough to cut through the target material. For example, the blade of a steel knife is ground to a bevel so that the two sides of the blade meet. This edge is then refined by honing until the blade is capable of cutting.
Blencathra is a popular mountain, and there are many different routes to the summit. One of the most famous is via Sharp Edge, a knife-edged arête on the eastern side of the mountain. Sharp Edge provides some good scrambling for those with a head for heights. Hall's Fell ridge, on Blencathra's southern flank, also provides an opportunity for ...

In machining a chamfer is a slope cut at any right-angled edge of a workpiece, e.g. holes; the ends of rods, bolts, and pins; the corners of the long-edges of plates; any other place where two surfaces meet at a sharp angle. Chamfering eases assembly, e.g. the insertion of bolts into holes, or nuts.
A body with a sharp trailing edge which is moving through a fluid will create about itself a circulation of sufficient strength to hold the rear stagnation point at the trailing edge. In fluid flow around a body with a sharp corner, the Kutta condition refers to the flow pattern in which fluid approaches the corner from above and below, meets ...
