It may seem blasphemous to suggest such a thing, but unless you are a contractor on the go, your tools probably don’t leave the confines of your workshop very often. If you need them for a project around the house you can simply carry them there, and they don’t need extra protection during this 15 second trip.
Instead, store your power tools in cabinets and drawers, which will make them easily accessible and allow you to throw away the tool cases. Keep all the instructions, warranty information and accessories, though. You can throw them in a ziplock bag and label the bag with the name of the tool.
