If you use your portable power tools primarily in your workshop, tool cases are an inefficient means for storing them. Instead, use workshop built storage for organizing your tools.
In this video I explain the reasons for throwing away tool cases, and show how I've created custom drawer storage for various tools.
Please note, the views expressed herein represent my philosophy regarding the value of tool cases within the workshop. Everyone's needs are different, and for some, my proposition makes no sense. Perfectly understandable.
