Does anyone use two razors and blades for shaving: 1) a smooth blade for WTG and XTG, and 2) a sharp blade for XTG and ATG. I am finding a smooth blade (Personna Labs, Astra, Voskhod, etc) in an EJ89 and a sharp blade (feather, silver blue, yellow sharp edge, etc) in an adjustable works well. And the two types of blades have different life spans with smooth having long lives and sharps short ones. Anyone else doing this and if so, what razors and blades have you found effective?
