I have the matching stand, and I only own three razors.
I don't do rotation.
For years the Rex Envoy was my only Razor. When it broke I picked up a game changer .84 OC to keep me shaving while it made its way to Arizona for repair and back.
As the service was good, I bought a Konsul from them last week. It'll be my new daily razor. The other two will remain in storage in their boxes, only to be used in the event the Konsul breaks.
There's a long, deep windowsill the bathroom. It sits there (where the air can get at it) along with a brush, a splash and two soaps and an alum block.
The brush gets rotated. The soaps get rotated. The splash gets rotated. The razor remains constant.
