The wood and pliable material is bonded to form a unitary product and grooves through the wood sheets are spaced at intervals to facilitate bending of the product at the grooves. The sheet-like product is used to make wood honeycomb and corrugated wood by positioning grooves at predetermined locations on the product, bending the product into a certain configuration. In the case of honeycomb, adjacent strips of the product are adhered together in such a way as to form polygonal cells. To make corrugated wood one configuration has a series of high and low ridges secured to a facing skin. The methods of making the wood sheet-like product comprises inserting a pliable material between two sheets of wood bonding the sheets together and cutting a groove through the wood sheets but not through the pliable material.
