With all due respect to the makers of real and useful multi-tools, and with no constraints of what would actually fit in a multi-tool, well, I put a travel bottle of hot sauce in the handle, among other things. I believe we have to dream big (but I also believe it is quite probably impossible to stow a pizza cutter inside the handle of any multi-tool.)
More stuff like this in my new book, Bears Don’t Care About Your Problems, out now.
