The Leatherman Tread tool is a wearable multitool, with small tooled links that combine to form a bracelet or watch band. Each link contains two or three tools, so the whole assembly gives you a complete set of screwdrivers, hex drives and box wrenches. It was released in 2015.
There are no similar tools from Victorinox or Wenger.
