Maintain your tools rust-free
A true proper keeps his tools where they are easily accessible. This is one of the reasons a toolbox is rarely locked. This also contributes to many utensils forming rust, which over time kills them. Place some silica gel among the tools to keep the humidity in the toolbox at the lowest level and you will never have to worry about them rusting away.
Technical data: The high specific surface area of silica gel enables it to readily absorb water, making it useful as a desiccant (drying agent). Silica gel is also referred to as moisture absorbing and can be appropriate if the microscopic structure of the gel is overlooked, as in silica gel packets or other products.
