This is a beautiful Don Huffman Custom folder with 2 blades. This knife has two blades made of AST-34 and nickel silver bolsters and liners. The serial number on this knife is 03. This knife is 3 ¾ inches long when closed and 6 ¾ inches long when the main blade is fully opened. Both blades sit deep and well centered when closed. The handles are jigged bone, not sure what type of bone it is. The walk and talk is perfect on this knife. The fit and finish on this knife is on par with anything that Jess Horn or Frank Centofante made.
