This is why when the tool case that came with my Lee Oskar toolset started to fall apart (due to a lot of use, carrying around, etc), I went to Brad to find a solution.
I showed him Richard Sleigh's video, because his roll-up tool case (made by Cumberland Custom Cases) seemed like a great idea. I asked Brad to build his own take on such a case. This is what he came up with.
The case can rolls up and has pockets for the tools. I rarely carry all of my tools with me though, so the case separates into two sections. If I only need my basic tools, I take only one section with me.
