While the Boker USA Beer Barrel Copperhead Folding Pocket Knife is not quite as "aged" as the brewing industry, the same quality standards apply. The oldest evidence that beer was brewed in Germany comes from around 800 B.C. By the second century, beer was being traded commercially in Germany. In 1516, Duke Wilhelm IV of Bavaria enacted the Reinheitsgebot, or the "Purity Law," which regulated the brewing of beer in Germany. To commemorate this common interest, Boker is introducing a series of traditional Boker USA Beer Barrel Copperhead Pocket Knives with handles made from genuine German ale/beer barrels, handcrafted in the Solingen factory. Boker USA Beer Barrel Copperhead Folders have patterns that include solid nickel silver bolsters, brass liners, carbon steel lades and the resurrected old Tree Brand blade etching. The Boker USA Beer Barrel Copperhead Pocket Knife makes a great item for the collector or everyday user.
