The other evening I decided to test out one of my razors in my collection. ( I generally have 2 sets of razors, the ones I have as collectibles and the slightly lower quality duplicates that I have that I use.) I was having an already bad day and decided that a good shave followed by a glass of Johnnie Walker would be a stress reliever before turning in. Well with out having a duplicate I took one from my collection, while crossing through the kitchen my new condition Gillette Tech 3 fell to the floor and broke the threading from the top plate. Lesson learned: Never use part of your collection. Always one use the duplicate.
