The Schneider gramil is made to be used for cutting binding/purfling ledge. The anodized body of the tool bears against all surfaces – top, side, and back – for scoring the binding/purfling ledge. We watched Richard Schneider, the designer of this tool, using a comfortable pulling action to make his gramil cuts in a top and chisel out the binding ledge in just a few minutes. The gramil can also be used to make the preliminary cuts before routing. The knife holding arm is adjustable for depth of cut from the top (a very handy feature), and the knife blade is adjustable and held securely with an Allen key. The body is machined from aluminum, black anodized, with dimensions of 3” x 1” x ½”; the steel arm is ½” x 3” x ½”, and helps give the gramil a comfortable balance. Blades are made by Ron Hock.
Use the flat side of the tool on all binding surfaces with the exception of the waist and cutaway areas, where the curved section should bear against the surface. The flat side of the blade should always be toward the side of the material where you want your cleanest cut.
