Here's a tip I learned in my time in the Marine Corps. You travel regular and use a shave kit bag. The old plastic razor box is bulky or long ago broken. How do I protect the blade in the DE razor as it rattles around in the bag and prevent cuts as you reach in? It works on those new cartridge razors too if you must use them.
Take a 35mm plastic film canister. in the center of the side, cut a round hole the diameter of the razor handle where it will go through. Now from the center of the hole, make a straight cut all the way to the end of the open container. Now slip the razor through the straight cut, it will flex to allow passage, to the hole. put the cover back on the film container and you have the head surrounded by the container and nothing can contact the blade. Hope this helps.
