The company's products include fixed blade knives, folding knives, swords, machetes, tomahawks, kukris, blowguns, walking sticks, and other martial arts items and training equipment. Their knives are used by military and law-enforcement personnel worldwide.[2][3]

Many of Cold Steel's products are designed by company President Lynn C Thompson and based upon traditional knife designs from all over the world, but Cold Steel has also collaborated with custom knife makers such as Andrew Demko, Phil Boguszewski, Zach Whitson, Steven Likarich, Keith Dehart, Rich McDonald, Bob Koga, Fred Perrin and Lloyd Pendleton on certain designs.[8]
