I saw in the double edge razor sub-forum that a member who has been on here since 2016 had never had a Merkur before so he bought a 34, and it got me thinking about common shaving products that I have never used. I'm sure that there are more than a few, but the one that came to mind was TOBS, an old standard in wet-shaving that I'm sure most have at least tried once. Feel free to tell me about TOBS, but also share the common software and hardware that you haven't used before.
