This is an instructional video lead in for those who do marquetry/inlay and have the need to cut perfectly straight line cuts in their project. I have taken on a project that requires many straight lines. An O blade is used to cut close to the intended straight line. While the project is still in packet form and the pieces cut out and in its tray, the packet is stabilized in a vise, a file is used to reduce the material to the exact line. The video will give a clear demonstration as to the technique. Additionally, remember the tortoiseshell is faux.
