We needed a material that would machine cleanly and that was lightweight and aerodynamic. It is also moisture resistant, so it won’t deteriorate and will keep its integrity within the board. Working with Celtec expanded PVC saves on the production costs of having to machine-mold the wedge. In a few simple steps, we cut the Celtec wedges on a band saw, plane them smooth and attach them to the top of the wood, below the foam grip. We then stamp it with Icon’s TruConcave patent logo.
