Hand hook for warehouse work.

It becomes part of your hand! Assist cargo hook "Toshin-style" .

This traditional Japanese hook tool is called a “Tekagi”, widely used at fishing ports to handle fish and cargo. This cargo hook was created for use in warehouse loading and unloading work.
A assist cargo hook is a tool with a wooden handle (usually oak) and a metal hook at the end for hooking luggage to carry. The claw is forged and durable, has a sharp piercing edge, and the grip fits in the palm of the hand, making it easy to apply force and less tiring to use for long periods of time.
The Toshin-style assist cargo hook is used for loading and unloading bags of rice, coffee beans, etc. in warehouses.
