In his work as a carpenter/builder, David grew tired of having to cut out hinges with a hammer and chisel. This led him to create the Hinge Jig which he originally patented more than 10 years ago. He has been refining the Hinge Jig ever since and now has the device ready for the market. He has already sold about 4000 Hinge Jig Devices.
