Purfling Cutter — Lutherie Encyclopedia

Purfling CutterType: toolA specialized double-bladed cutting tool that scores parallel lines for inlaying purfling strips around the guitar body.## Description A purfling cutter features two parallel blades set a fixed distance apart, mounted on an arm that references against the edge of the guitar. The blades are typically small knife-style cutters that can be adjusted for width (to match the purfling strip) and depth (typically 1.5mm to 2mm). Some designs use a fence that rides along the side of the guitar, while others use a central pivot point for cutting around curved sections. ## Use in Lutherie Purfling is the decorative and structural inlay that runs around the perimeter of the top and back plates, just inside the binding. The purfling cutter scores two parallel lines into the spruce or cedar top, after which the waste between the lines is removed with a small chisel to create a channel. The purfling strip is then glued into this channel. Accurate cutting is critical because the purfling line is one of the most visible details on a finished guitar. Classical and steel-string acoustic guitars both use purfling, though the styles differ. ## Selection Guide The Stewart-MacDonald purfling cutter is widely used and affordable. Luthier-supply specialists like LMI and Dictum also offer quality options. Key features to look for include fine depth adjustment, secure blade locking, and a smooth-running fence. Some luthiers prefer a Dremel-based routing approach, but hand-cut purfling channels generally produce cleaner results with less risk of tearout. Budget 20 to 60 dollars for a dedicated purfling cutter. ## Tips -…
