While building his home in 1986, Craig Sommerfeld, a tool and die maker, came up with the idea for "Craig’s Jig," a pocket-hole joinery jig that allowed him to attach cabinet face framing from inside the cabinet, with the screws hidden from view. From that simple concept, he developed the versatile Kreg jig system, which uses drilling guides to position counterbored screws, creating strong, concealed pocket-hole joints in a straightforward, consistent manner.

Since then, Kreg has developed a broad line of workshop accessories, from router tables to work-holding clamps, designed to improve the accuracy, convenience, safety and versatility of common tools. They are well designed and durably constructed.
