This is a rare first variation MartoM9, made by Phrobis International in 1990. 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 M9 Bayonet The Authorized History. Knife is unused in near mint condition (light handling) complete with scabbard and sharpening stone, note that sharpening stone is not glued into place, which has released over the years. Comes in the box, which has some wear. Quite a scarce knife!
