This is MUCH too simple my friend. Here in the USA we need to keep layers of lazy people werkin' at nuthin' all day!A paper journal and a magnet to keep blades not loaded in a razor. It got tricky when I was trying out many blades but nowadays I have a maximum of 2 DE blades in usage. I try to shave with every razor 3 times in a row and keep the blade loaded in that one razor.
My journal simply reads:
Date Razor Soap/Cream Blade (usage) Result
07/21 Fatip Open Comb Slant, Lea Menthol, Personna Platinum (2), DFS
I have one Butler to load, one Butler to record, and one Butler to remove and dry the blade.
