If you want to incorporate curves into your project, there are a few ways to do it. You can cut wood into thin strips of veneer and build up a curve layer by layer, you can steam the wood, or you can cut closely-spaced kerfs. Using KerfKore panels is another way to skip these time-consuming methods and get down to building.
As the name implies, KerfKore panels are a sheet material with a core consisting of thin strips of solid material such as particle board, MDF, or plywood with spaces or kerfs between the strips. This allows you to create curves with radii as tight as 3-1/2″. They use black latex-impregnated paper for the face of the panels and leave the other side of the panel open.
KerfKore comes in 1/4″, 1/2″, and 3/4″ thick panels. Pricing varies based on the thickness and size of the sheet; for instance a 48″ x 48″ sheet of 1/2″ KerfKore runs $54 before shipping. Of course, shipping sheet goods is going to cost you a bundle.
