This is a right hand marking knife made by Narex Tools of the Czech Republic. This knife will draw a much finer line on wood than an awl or pencil. It is beveled on one side only to keep the cut absolutely tight to your rule or square. Defines an exact line for starting a chisel or saw blade. Designed to mark a line on the right side of a rule. Blade is 1/2 inches wide by 1/8 inch thick and 6 1/4 long. Made from super hard tempered and hardened high speed steel. Will take and hold an excellent edge.
