    The Viking Knives Fighter Model 12 is a custom fixed blade knife attributed to American knifemaker Jim Eriksen and presumably made between the 1990s and the early 2000s, although the exact date is not documented. The knife features a 180 mm blade with a slender profile, pronounced tip and distinctive asymmetric single-bevel grind: one side of the blade is flat, while the opposite side features the main bevel. Its construction includes a straight metal guard, black handle scales secured by two pins and a shaped pommel with a lanyard hole.
     
    The opposing "VIKING" and "ERIKSEN 12" markings, together with the handmade leather sheath branded Viking Knives, support the attribution and enhance its appeal to collectors of American custom knives.

    Intended use: collection, display and utility use compatible with its size and geometry
    Production type: handmade custom
    Country of manufacture: United States
    Blade: 440C
    Blade finish: satin
    Handle: G10 scales
    Blade length: 180 mm
    Blade thickness: 6 mm
    Overall length: 303 mm
    Weight: 507 g
    Guard: metal, with straight arms
    Sheath: stitched black leather, with rear belt loop and Viking Knives marking
    Packaging: -
    Notes: blade with asymmetric geometry, flat on one side and bevelled on the opposite side. "VIKING" and "ERIKSEN 12" markings on the blade. The number 12 presumably refers to the model or pattern, but the official designation has not been verified against an original catalogue. Surface marks consistent with previous storage or use are present. Production date not stated.

    The asymmetric grind is one of the specimen's most distinctive technical features and reflects a specific construction choice by the maker. Together with its large size, original branded sheath and clearly legible markings, it supports the knife's position within American custom production intended for collectors. This configuration is particularly appealing to enthusiasts of handmade fighters and unconventional blade geometries.
