Unlike general tool manufacturers, we are a specialized manufacturer focused on "drive tools" such as socket wrenches and ratchet handles. Our product lineup includes various sockets (manual and impact), ratchet handles, T-type wrenches, and the next-generation compact tool series "Z-EAL." We achieve extremely high dimensional accuracy and durability through in-house production (completely made in Japan). The ratchet features a "light free rotation torque" and reliable gear engagement. Our thin-walled design is intended for narrow workspaces, and we have unique mechanisms such as the "nut grip" that holds bolts securely. We have earned high trust from professionals in automotive maintenance, aviation, and industrial machinery both domestically and internationally.
