K & H wedges have been a logging tradition since 1962. K & H wedges are also known as "red head" wedges because of their distinctive head color. K & H wedges are made from very hard high impact ABS plastic and have a light textured surface to keep them from slipping. Many loggers claim that K & H wedges are the easiest plastic wedge to drive and have great lifting power. As with all felling wedges, use safety glasses when driving them.
