Glass and mirrors
Bevelled edges are a common aesthetic nicety added to window panes and mirrors.
Geology
Geologists refer to any slope of land into a stratum of different elevation as a bevel.
Sports
In waterskiing, a bevel is the transition area between the side of the ski and the bottom of the ski. Beginners tend to prefer sharp bevels, which allow the ski to glide on the water surface.
In
Disc Golf, the 'beveled edge' was patented in 1983 by Dave Dunipace who founded Innova Champion Discs. This element transformed the Frisbee into the further-flying golf discs the sport uses today.
Cards

, wafers have two typical edge types: a slanted beveled shape or a rounded bullet shape. The edges on the beveled types are called the bevel region, and they are typically ground at a 22-degree angle. While it is not possible to create a complete and functional
die with the bevel material of a wafer, the area is still routinely processed throughout the manufacturing cycle to remove unwanted masks, residues, and films from the edge of a wafer that could potentially become a source of defects between manufacturing steps.
Welding
Beveling and chamfering (along with other profiles) are applied to thicker pieces of metal prior to welding, see
Welding joint#V-joints. The bevel provides a smooth clean edge to the plate or pipe and allows a weld of the correct shape (to prevent center-line cracking) to join the separate pieces of metal.
Simple bevels can be used with a backup strip (thin removable sheet behind the plate joint) with chamfers (and a small land) being used on open root welds. Particularly thick plate will have a J-shaped chamfer or U-shaped groove to reduce the amount of welding filler metal used.
Cruciform joint
In metalworking, a welding joint is a point or edge where two or more pieces of metal or plastic are joined together. They are formed by welding two or more workpieces according to a particular geometry. There are five types of joints referred ...
preparation can involve a double bevel to permit full penetration of each weld to the other, removing a possible void space in the center.
