Based in Nagaoka City in Niigata prefecture, 4-BIT merges age-old traditions with modern techniques to produce tools that fit into the modern lifestyle. Forged Paper Knife is an understated piece of refined craftsmanship that stems from the tradition of hammered knives, from the era of the Warring States in Japan history. The ancient sword-making techniques are now used in the making of carpentry tools. The forged knife’s ridge is made of high-quality, 100-year-old iron, with the cutting edge shaped by modern technology. Although it is a paper knife, it retains the sharpness of a Japanese sword and can be used for various purposes such as crafts and cooking.
