The Bench Hook and the Shooting Board are both traditional woodworking devices which have been used for centuries. Many years ago, Greg Miller put the two together into one double-sided device. They are extensively used at our Heritage Woodcraft Centre as a versatile tool in combination wiht saws, planes, and much more.
They are sacrificial surface which protects your bench, kitchen table, or whatever it is that you do your woodworking on!
They also assist with work holding in a range of functions, in particular with sawing (the bench hook side) and with planing (shooting) ends square (the shooting board side).
What a wonderfully versatile tool! Every woodworker and aspiring woodworker needs one!
