Extrema Ratio presents the Harpoon F XXV Anniversarium knife, a 25 pieces limited edition of the historic model Harpoon F Tiger Tech
The Extrema Ratio Harpoon F XXV ANNIVERSARIUM is a multipurpose knife meant for tactical and survival use. The blade’s modified spearpoint profile makes it effective both as a cutting and piercing implement.
Blade thickness is 6,3 mm (0.25”) making it very sturdy and resistant, while the hollow ground, distal tapered profile makes it light and offers an excellent balance.
Milled out of a Böhler N690 bar, it is heat treated to 58HRC, offering high edge retention and high toughness at the same time, and has a plain edge with false saw teeth on the back meant to enhance its performance when mounted on a shaft to be used as a harpoon.
The 21 cm (8.27”) length, unusual for an Extrema Ratio knife, has been designed to maximize effectiveness in all kind of uses.
The blade has been given the Black Warfare finish, characterized by a Geotech Camo pattern, the innovative and original camouflage pattern by Extrema Ratio, realized by laser etching of the surface, which revises and evolves what 25 years ago was the Tiger Tech Camo finish.
The grip is the usual, ergonomic Extrema Ratio grip, made with Forprene, a polymer that offers excellent grip with good vibration dampening properties, for comfortable, prolonged use in the most strenuous circumstances.
The black cordura sheath has loops for both belt and tight harness.
A pocket with a Velcro flap is provided to hold a honing stone.
The knife is delivered in a sturdy Polypropylene case which carries a metal plate bearing the progressive numbering of the limited series.
The black cordura sheath is provided together with the case, built in a separate packaging.
