When wife tries to open cabinet door under sink : Thou shalt stop shaving, hold razor away from face. Better yet, when wife enters bathroom, stop shave or your doomed to get a razor cut.
Thou shall not keep asking those who get longer then 12 shaves per blade to change their shaving habits unless you're positive they need to stop using the blade sooner and can explain why the shaver needs to change blades before the shaver does. theMost of these people like me use one side up for 7+ shaves then flip the blade to the bottom side.
I think our ancestors in the Gillette as the main seller of shaving equipment era, so 1900 to WWII got advice from the ads with the tips on how to use the blades/how to shave with one in the ads like for creams considering the Safe-T-Shavers were newer than straight edge. From what I have read about in The Man and his Wonderful Shaving Device by Russel Adams, some would go and try to use a blade for too long trying to strop the blade and later re-hone the one blade (not just a thing during the 1930's and WWII but early on people tried to do this with the Treet mild steel style Gillette blade) or actually have a place bevel and sharpen the top plate of the 3 piece shaver to a sharp edge and use the shaver this way without a blade stropping until they needed to just re-hone the top plate that is now used as the blade where some found the bottom plate useless because they would screw the top plate all the way down to the bottom plate on the newer models in the 1920's after WWI that did not just fit in place like the older models.
Wasn’t the Sahara desert heavily forested and densely populated prior to the earliest recorded usage of Clubman?
