This survival knife prototype was made in Seki Japan circa 1980s by Tak Fukuta. It features a stainless steel blade with a hollow metal handle. It is a factory sample prototype and is sterile (unmarked). Tak Fukuta was the first Japanese member of the American Knife Maker's Guild, and apprentice to Bob Loveless. He hand crafted fine quality knives that impressed his mentor. Over the years, his factory in Seki, Japan also produced knives for Parker, Valor, Gutmann, Explorer, Frost, and Browning among others. After his passing, several vintage old stock models were found at his warehouse. This is one of these rare finds.
