Haiku, the traditional knife-line by Chroma Cutlery, Inc. Haiku knives are manufactured in small Japanese knife factories out of high-grade modern steel. Borrowing from an ancient method, a bamboo peg (''mekugi'') is inserted from the side into every Haiku knife where the tang and handle are joined for added stability. Traditional sword smiths in Japan use this time-tested technique when crafting swords like those once used by the samurai of medieval Japan. Haiku - the Japanese knife with the honoki-wood handle.
