I have backups for all my favorites (Super Speeds, Fat Boys, Slims, Old Types, and Black Beauties), so the only two that I don't have backups to that I'd replace would be my Big Fellow Old Type and Aristocrat. I'd add my New Improved Tuckaway, but I haven't shaved with it yet as part of a "Pandemic Shave" promise. I shaved with my 1918 that was there when the last pandemic began and haven't used it since, and am holding off using the Tuckaway for the first time until we turn the corner on the current one. Usually it's days after acquiring a razor til first use, but it's nearly a year and still in the case; so I'm anxiously awaiting.
