Vintage Stacked Handle Fighting Knife/Dagger

This item is a vintage fighting knife or dagger, characterized by a stacked handle construction and a double-edged blade. The blade metal appears to be carbon steel due to its dark, oxidized patina, suggesting a lack of regular maintenance or intentional aging. It has a narrow, pointed profile, indicative of a stabbing weapon, and shows visible wear including pitting and discoloration across its surface. The hilt features a small, simple metal crossguard, likely made of nickel-plated brass or steel, which has also developed some surface tarnish. The most distinctive feature is the handle, which is crafted from stacked materials, possibly comprising segments of clear Lucite or plastic separated by colored rings of red, white, and blue, perhaps suggesting a patriotic motif or military association. There are also metallic spacers, likely aluminum or nickel, integrated into the stacking. The pommel is a rounded metal cap, exhibiting similar tarnish to the crossguard. The craftsmanship of the stacked handle, while functional, appears to be of moderate quality, with some minor inconsistencies in the alignment of the stacked elements. There are no discernible maker's marks or signatures visible from the image. Given the style of the stacked handle and the materials, it likely dates from the mid-20th century, possibly post-WWII to the 1960s or 1970s. The overall condition suggests significant age and use, with the blade showing the most pronounced signs of wear and corrosion, impacting its aesthetic appeal and potentially its structural integrity. The handle shows minor scuffs but retains its original colors.
