This is a traditional finish going back hundreds of years. The finish is achieved when the tannin rich lumber is exposed to ammonia fumes. The wood develops a dark, rich brown that penetrates deeply into the wood’s surface, meaning it cannot be worn off with use! We finish the piece with boiled linseed oil, another traditional technique for bringing out the luster and vibrancy of the natural wood.Our normal grip cross section is a 1-1/8″ tall and 3/4″ wide oval shape that tapers to a 3/4″ round end that fit up to our pommels perfectly. Choose length and tang slot size.
