My father in law was asking me today what I shaved with. He explained he's been getting pimples and rash on his neck. He knew I didn't use cartridges but that's about all. I gave him an Edwin Jagger DE 89, a Semouge 620, ten Astras and a shaving mug with soap. I tried to give him a quick and dirty tutorial, not sure how much sunk in. We will see how he gets along.
