Rob Bayley

Rob Bayley is an English forger of hunting and survival knives. His most famous knife was "The Signature Bear Grylls Knife," which was sponsored by Bear Gryllz on the Discovery Channel show Man vs Wild until November 2009. The knife has since been referred to as the S4 Survival Series knife. It is forged from RWL34 steel.
His knives are no longer available to the general public, but continue to sell for very high prices on online markets, resulting in the production of counterfeit replicas.
