Ceramic bodies can be made by providing an initial green body of ceramic; and machining the initial green body to provide a machined green ceramic body. Embedding the initial green body in an embedding mass can be avoided. The initial green body can be bisqued, infiltrated an adjuvant such as machining wax, removing the infiltrated body, and machining it. Highly detailed ceramic products can be generated. The machined green ceramic body may be fired and/or further processed to provide a more finished ceramic body. Examples include a femoral component for a posterior stabilized knee implant, a component body for an artificial rotation device containing knee implant prosthesis a dental implant or bridge, an ice skating blade, and so forth. Zirconia ceramics are advantageously employed, for an example, Mg-TTZ.

The present invention discloses a coaster cycle having a front half which works similarly to a bicycle wherein it has handle bars that turn the front wheels. The front wheel turns left and right and also leans in both a left and right direction. The front wheel leans left to right and is connected to the rear wheels by a frame having multiple pivotal couplings so that the rear wheels lean left or right with exactly the same angle as the front wheels. The leaning of the front and rear wheels in concert gives the frame a unique design which allows it to make left and right high G-force turns in a very stable manner. Additional embodiments are disclosed which comprise twin, internal combustion engines being placed on the rear wheels of the vehicle in order to power the vehicle which also have independent thumb control throttles for controlling the rear wheels individually. An additional embodiment comprises having snow skis attached to the underside of the vehicle to allow it to be used on snow and also having ice-skate like members attached to the underside of the vehicle to allow it to be used on ice.

A skate blade has a front curved section having a front balance point, a rear curved section having a rear balance point, and a middle section having a center balance point. Each balance point is a point on the skate blade over which a skater's center of gravity lies depending on the skater's position. The skate blade is shaped such that the middle section is substantially flat. Additionally, the blade is shaped such that more of the blade extends away from a blade holder at the rear balance point than at the front balance point.
