This is a rare first variation M9A1, made by Phrobis International in 1990-1991. The blade was made by Marto, but the rest of the knife and the sheath was made using the USA Phrobis parts. All from this variation were made this way, according to Rich Neyman, Author of M9Bayonet The Authorized History. Knife is in near mint condition (light handling) and comes with the sheath, which has the proper Phrobis dolphin indicating first variation.
