A toolbox is used to store hand tools and is generally used by woodworkers and carpenters to place and store their hand and power tools in a organized way. During working it provides a convenient access to the tools.
The basic difference between a tool bag and a toolbox is that latter is used to store tools which are heavier in weight and have more storage type options.
A handle is attached to the toolbox which is used for lifting and moving. The handle comes with the foldable and pull out option. For locking purpose two clip type locks are used for secure locking. In some toolbox two wheels are attached to it which helps in moving it from one place to another. The toolboxes are often water resistant which prevents water to enter into the toolbox and provides a dry storage.
