Metals are better kept in a metal cabinet while things like saw are best kept in a holder to avoid a domestic accident. They should be well arranged so that they don’t touch each other.
Those that can generate moisture, rub them with little oil or grease before storing; this helps to prevent rust.
Don't just throw them anywhere you see; have a designated location where you store them.
They should as well be kept away from the source of direct sunlight, dust and moist.
