CQC-6

The CQC-6 (Close Quarters Combat — Six) or Viper Six is a handmade tactical folding knife with a tantō blade manufactured by knifemaker Ernest Emerson. Although initially reported as the sixth design in an evolution of fighting knives and the first model in the lineup of Emerson's Specwar Custom Knives, Emerson later revealed that the knife was named for SEAL Team Six. It has a chisel-ground blade of ATS-34 or 154CM stainless steel and a handle made of titanium and linen micarta. The CQC-6 is credited as the knife that popularized the concept of the tactical folding knife.

Specifications

The CQC-6 has a 3 5/16" long blade. The handle is 4 5/8" long making the knife close to 8 inches in length when opened. The butt-end of the knife tapers to a point and features a hole for tying a lanyard.

The blade profile of most CQC-6's is a Japanese chisel ground tantō with a single bevel or zero-ground blade sharpened on only one side. Early models have a buffline similar to a hamon found on a Japanese Samurai Sword due to a leather buffing wheel used by Emerson to finish his blades. Unlike the typical Japanese chisel-grind, Emerson's grind is on the left-side of the blade as opposed to the right-side.
