The present invention provides a hot knife, which includes a blade, a heat source, a handle, and a power source. The blade includes a central portion extending along a central axis, two wing portions integrally extending outwardly from two opposite sides of the central portion in a radial direction of the central axis, and a chamber defined by inner walls of the central portion and two wing portions. The heat source is disposed in the chamber and is adapted to supply heat to the blade. The handle is attached to the blade. The power source is disposed in the handle and is electrically connected to the heat source.

A surfboard includes a core covered with a laminate and having curved perforations in the deck area and the tail area of the surfboard, in order to prevent air blisters from forming between the core and laminate. The curved perforations are deformable under pressure to minimize the opening of the perforations to inhibit liquid from entering and maximizing under zero pressure to allow the maximum amount of trapped liquid and gasses from escaping. The core is formed from an extruded closed-cell polystyrene foam block that has been shaped by restraining it against a shaped form using shaped restraining tools and straps, and heating it; and by cutting using a hot wire. The core is laminated with FIBERGLAS and epoxy resin, and the perforations are formed using a perforating tool that has a planar or curved working surface and one or more heated needles extending perpendicularly from the working surface.
