Vietnam Era Survival knife; Hackman of Finland.
Designed by Ken Warner and Pete Dickey; this rare knife was made during the late 1960s and early 1970s. Only a few thousand were made by Hackman with a 1/4" blade made in Finland, with the majority produced by Garcia in Brazil with a 3/16" blade. The Hackman Survival Knife was intended for private sale to military personnel bound for Vietnam. The Randall Model 18 had made the hollow handle sawback popular with the troops, but Randall could not keep up with demand. Like the Randall this knife featured a watertight hollow handle and a massive 1/4" thick stainless-steel blade.
This knife and sheath are an amazing combination. The Hackman made blade shows no use with only a small scratch on the pommel and finger guard. The sheath is not the original but a sturdy leather replacement with a small pouch for a sharpening stone. Judge the condition for yourself from the photos.
