I have 3 plastic drawers on a small wooden shelf in our bathroom. Top little drawer is full of the different blades, second is the different razors and third is odds and ends of shaving, such as extra soap, an extra brush, a couple of SE razors, stick.... etc. In that drawer I keep a fine width magic marker and after I shave take out the blade, pat it dry and put a single | on it denoting I used it, || would mean 2 and ||| means 3 and so forth. Then I wrap the blade back up in the wrapper and merely store it in that drawer. The razor used is wiped on the outside and leans up againt my wife's fingernail(etc) box sitting on top of the 3-drawer set, and it sits on a folded wash cloth and stay there until next morning,when I put it away. It lets the water drain and dry from the razor before I put it back in the drawer. Quick wipes with the hand towel to make sure all things are bright and shiny and then back in the drawer it goes. The marks on the blade just let me know how many times I've used it if I want to use different blades and different razors during the week. I can always see how many times this blade, or that blades, has been used.

I've got some used blades that are "in the can" than I'm dulling the edges on so I can mark on them the razor's date code and put that dulled dry blade into the corresponding razor and put it back in the drawer. I don't keep sharp blades in the razors, only the ones with the date code eg Y-2 1953 2nd, written on them. Keeps a collection of razors available for seeing what year and so on they are without having to look it up every time.
