Other models followed in the Specwar line bearing the CQC Series moniker, including the CQC7 which is another chisel-ground tantō-bladed folder similar to the CQC6 but with a saber-type handle shape. The CQC8 ("Banana Knife") was a folder inspired by Bob Taylor's Warrior Knife and William F. Moran's ST-9 is used by British SAS troops. The knife has the distinction of being the first folding knife that was designed to be ergonomically correct in both forward and reverse grip. Its users refer to it as "the finest fighting knife ever developed". The CQC9 ("Eagle Knife") is a reverse-curved hawkbill blade developed as a backup weapon for an American law enforcement agency; it also has an opening hole in the blade licensed from knife manufacturer Spyderco. Although Emerson has standard models for these custom knives which progress in order to CQC16, each one is made individually by hand.
 Popularizing the tactical knife
While not the first knifemaker to build what is known as a tactical folding knife, Emerson was one of several makers who popularized the concept of the handmade tactical folder in the 1990s. Emerson's knives also began appearing in the Rogue Warrior series of novels written by the founder of the US Navy's SEAL Team Six, Richard Marcinko, which helped fuel interest among collectors.coloured contact lensescalderas de gas
