Hand tool for shaping violin ribs — a dedicated shaver for producing clean, consistent ribs, including those made from resistant materials. Key benefits Precise, repeatable shaping: Two aligned blades and a secure upper screw hold blade position for accurate cuts and consistent rib profiles. Works with tough materials: Designed to shave and trim violin ribs made from resistant/durable woods and laminates without excessive force. Better results for beginners and enthusiasts: Simplifies a difficult step in lute­rire work so hobbyists and learners can achieve cleaner edges and reduced rework. Main features Two-blade design with an upper screw that locks the blades together for stable, controlled shaving. Two holes for a reamer to assist internal shaping and finishing where reaming is required. Intended specifically for making violin ribs (sprossen) and related small-scale wood forming tasks. How this tool solves problems Eliminates inconsistent hand-planing by keeping blades aligned and secure, reducing chatter and uneven edges. Handles harder or more resistant rib materials so you can work without frequent blade stoppage or tearing. Lowers the learning curve for beginners by giving a reliable cutting geometry that produces predictable results. Typical applications Building new violins: shaping and trimming ribs during assembly for accurate fit and clean joins. Repair and restoration: reshaping or replacing damaged ribs on older instruments made with tougher woods. Teaching and hobby projects: ideal for luthier classes and personal workshops where consistent, repeatable rib shaping is needed. Who should use it Violin makers, repair technicians, luthier students, and violin enthusiasts looking for a practical, easy-to-use tool for rib work. Recommended use notes Secure blade alignment using the upper screw before shaving. Use the two reamer holes when internal shaping or precise bore alignment is required.
