Interesting, I see several people here with a penchant for pens and wet shaving in some variety. You can add me in too! In my circles there’s actually a great cross-pollination - I met some of those guys through our interest in shaving, and then they started pipe smoking because of me.
These days I predominantly look for fountain-pens, and these days I mostly prefer single edge razors, a DE will crop up every now and then, or a nice ballpoint. I guess you could say I like beautiful old things that still provide great utility. Plus it’s a great sport to look for all of them them while thrifting. A good part of my enjoyment is nerding out on this stuff, doing the research, cleaning it and sort of spiffing it up a bit so it’s ready for another 50 or 100 years of use, then using it, or passing it along to a friend.
I also love HiFi (esp. headphones), I am building out my library which has now come to a couple thousand books, but that’s a different story altogether.
