VESSEL is producing and distributing VESSEL branded screwdrivers, driving bits, industrial tools, pneumatic tools and ESD-related products. VESSEL was founded in 1916 as Japan's first volume manufacturer of screwdrivers. With most ironworks at the time producing agricultural implements such as spades and hoes, the young company put in place a mass production system specialized for the manufacture of screwdrivers for industrial applications and began supplying its products to the market. In 1933, the company began emblazoning its products with the brand "VESSEL," meaning a large ship in English, as a signifier of their superior quality. VESSEL products have consistently met strict quality requirements as professional tools. Over more than 100 years of history, this rock-solid commitment to quality has anchored our operations. In terms of design, we strive to create products that all customers will find pleasant and comfortable from first-time users to professionals who make a living with our tools every day.
