Handmade in France by Arno, the Arno Carbur 2 solid carbide burnisher is the go-to burnisher for many woodworkers. It is the fastest and the most effective burnisher around. It has a polished cylindrical polished rod one side, the other side has a triangular section with a small radius designed for thicker scrapers or scraper plane blades. The handle shape protects from the scraper’s hopefully sharp edge… Comes with very good instructions and a leather wallet.
