I have the SS, but prefer to shave with a straight. Since I would need to stow the Feather, I might as well stow a straight and a strop. Now if only I could take my water softener.
The Dovo case is nice, well padded and holds two razors. You might try lining the "coffin" cases with anti-rust polyethylene - image attached. The Puma cases are nice.
And if you want to go retro with hone and strop...
