glass fiber reinforced plastic cutting are coated in micron-grade diamonds secured to a tough and durable resin, which is in turn connected to an aluminum plate or a foam hand plate, providing a much more powerful option for surfboard shapers around the world.

After the outline of an unfinished board, known as the blank, is finished. The shaper then goes over the board with a power planer to give its surfaces the contours it needs. After shaping with a hand planer, the board's surfaces are sanded with sand paper to give it the smooth and even surface it needs. However, recently sand paper has been replaced more often by diamond abrasives, which allow greater efficiency and longevity.

Because of wings material cutting, shapers that create a large number of surfboards have found that diamond abrasives (like resin bond disks) have been an ideal innovation. At the same time, not all shaping allows the use of power tools for sanding. Sometimes shapers need more precision and control. For this there are also abrasive hand pads for finishing and polishing surfaces quickly, effectively, and carefully. Because these hand pads are geared towards hand-use, they have a foam backing that allows them to easily conform to the sides, or the rails, of the surfboard. This makes hand sanding the surfboard faster, more effective, and much easier.
