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 ...
The mechanical advantage or MA of a wedge can be calculated by dividing the height of the wedge by the wedge's width: [1] M A = L e n g t h W i d t h {\displaystyle {\rm {MA={Length \over Width}}}} The more acute , or narrow, the angle of a wedge, the greater the ratio of the length of its slope to its width, and thus the more mechanical ...
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 ...
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. They have a plastic concavity in the sole, which allows the wearer to grind on objects such as pipes, handrails and stone ledges.
Straight grinds range from true wedge, through near wedge, quarter hollow, half hollow, full hollow, and extra hollow. As the grind gets more hollowed, the blade becomes more flexible and the edge more delicate, making it shave closer but require more skill in sharpening and use, and reducing its suitability for heavy beards.

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 ...
