Dymondwood handle material is made from domestic and imported hardwood veneers. The wood is then vacuum impregnated with color dyes and resins, then bonded together under high pressure. It is resistant to almost anything. When final sanding is done, just polish your knife handle with a soft buff and it is finished - no other finish is necessary. Blanks are 5" x 1 3/4" x 5/16".
