The class of wedges grew out of the need for a better club for playing soft lies and short shots. Prior to the 1930s, the best club for short "approach" shots was the "niblick", roughly equivalent to today's 9-iron or pitching wedge in loft; however the design of this club, with a flat, angled face and virtually no "sole", made it difficult to use in sand and other soft lies as it was prone to ...
Grinding is a sliding stunt performed in various sports such as skateboarding or inline skating. It involves sliding the body, rather than rolling the wheels, of the skate or board against the supporting surface.
For a wedge, this is given by 1/tanα, where α is the tip angle. The faces of a wedge are modeled as straight lines to form a sliding or prismatic joint. The origin of the wedge is unknown. In ancient Egyptian quarries, bronze wedges were used to break away blocks of stone used in construction.
A Sabre grind without a secondary bevel is called a "Scandinavian (Scandi) grind", which is easier to sharpen due to the large surface. The Finnish puukko is an example of a Scandinavian-ground knife. Chisel grind: As on a chisel, a single bevel-ground is only on one side, (ground often at an edge angle of about 20°–30°); the other remains ...
Grinding is damaging to materials which are not hardened for the specific purpose of the sport, as may be found in a skate park. The trucks are composed of a hard metal without lubricant or bearings on the grinding surface, so they literally do grind on the objects they slide across. Grinding can strip paint off of steel and wear down the edges ...
Soap was the brand name of shoes made for grinding, similar to aggressive inline skating. They were introduced by Chris Morris of Artemis Innovations Inc. with the brand name "Soap" in 1996 [1]. They have a plastic concavity in the sole, which is intended to aid the wearer in grinding on objects such as pipes, handrails and stone ledges.
Determining the fineness of a paint's grind is important, because too coarse a grind may reduce the paint's color uniformity, gloss, and opacity. [7] The Hegman gauge is widely used for this purpose because it requires minimal skill and only a few seconds' work.
For me, it was a grinding to a halt, until I could barely walk really... I took about a couple of years, a year-and-a-half of breaking myself apart; pretty medievally. And as I did so, I realized that that was helping me unravel my stance; and so now, I've just been investigating, or pushing myself to try to, to, take apart my stance so that I ...
