Taking inspiration from the classic "Trench Knives" from both World Wars of the last century, we have developed a tactical fixed blade that is suitable for today's modern day warriors. The unique "D" ring guard is made from reinforced 6061 aluminum allowing for an incredibly secure and comfortable grip while protecting the hand both from incoming attack and damage while striking or cutting an opponent who's covered in body armor, ammo, flashlights, magazines and gear! The thick 1055 carbon steel pommel is tapered for ferocious Punyo or Butt-Strikes, and the 7 1/2" SK-5 high carbon blade is available in either Double Edge or Tanto blade shapes. Additionally, the Chaos series is coated in black Tuff-Ex, aiding corrosion resistance and enhancing cutting power by reducing friction. They come complete with a tough Secure-Ex sheath, which features a belt loop for dependable, versatile carry. Specifications: Blade Length: 7 1/2"; Overall Length: 13 1/2"; Steel: SK-5 High Carbon; Weight: 17 oz (Approx.); Blade Thickness: 4.5 mm; Handle: 6" Long, 6061 Aluminum; Sheath: Secure-Ex Sheath.
