    Created in the early 1980s from the vision of legendary designer Al Mar, the 3004 “De Oppresso Liber” is much more than a knife: it is a symbol of tactical excellence and special forces spirit.

    Produced in a very limited series in Seki, Japan, this fixed blade knife was designed to meet the extreme standards of the U.S. Army's SERE (Survival, Evasion, Resistance, and Escape) units.

    The engraved motto — “De Oppresso Liber,” “liberate the oppressed” — directly echoes the ethos of the American Green Berets.

    Refined, robust, and now highly sought after by collectors, the 3004 represents one of the most iconic chapters in the history of modern military knives.

  7. Buck - Buckmaster 184 - 1984 First Production - PRIVATE COLLECTION - vintage knife

    Knife withdrawn from private collection, dates from the very first production in 1984 (in fact, it does not indicate the patent engravings, affixed in 1985 and does not indicate the production date, affixed only from 1986). Globally in good condition, it has marks on the blade and handle due to the normal passage of time and the very aggressive scabbard which, containing a spring-loaded metal foil, irreparably scratches the blade both in insertion and extraction - It still has the factory sharpening and comes with a compass in the tang and two harpoons already engaged on the guard branch; lacking instead the box and additional accessories - Checked and certified by our in-house laboratory.

     


    Intended Use: Sporting / Collection

    Type of production: Industrial
    Country of manufacture: USA
    Blade: knife made entirely of 425M stainless steel
    Blade finish: satin-finished
    Handle: hollow, stainless steel, with rear screw cap
    Blade length: 185mm.
    Blade thickness: 7.5mm.
    Total length: 315mm.
    Balance: set back from the guard branch
    Weight: 675g.
    Scabbard: black ABS
    Notes: The feature, patented, is the presence of two removable screw-on harpoons/hooks. The function of these is simple anchorage. In fact, this knife can be used as a throwing hook by attaching a rope to the ring on the pommel. The manufacturer guarantees a harpoon hold of up to 600 pounds. The Navy Seals, specifically, had requested a knife that could be used underwater in order to anchor the vehicles to an underwater attachment point, and that is the reason for the total steel construction.
