As we have seen, Saussure showed that a sign is not necessarily something that connects a word or name to a thing, but is in fact something which connects a sound or image to a concept. The sound or image is called a signifier.
The rift sawn rip cuts are perpendicular to the center of the log. In woodworking, a rip-cut is to sever or divide a piece of wood parallel to the grain. The other typical type of cut is a cross-cut, a cut perpendicular to the grain. Unlike cross-cutting, which shears the wood fibers, a rip saw works more like a series of chisels, lifting off small splinters of wood.
