I hadn't been familiar with Kirk Bosi's pipes until I saw a listing on eBay for a boxed set of unsmoked Signature Grade pipes, which were his higher grade. After researching his work and learning that his engineering and craftsmanship is excellent, I placed a bid and won at a surprisingly low price. Saturday morning bargain. I'm collecting pipes made by members of my pipe club, CPCC. So far I have an Alex Florov, a Kevin Arthur, and now two Kirk Bosi pipes. Unfortunately, I've never seen any of these fellows at one of our meetings, but I understand that Alex does come from time to time. He lives a good distance from our meeting site.
I listened to an old interview of Kirk by Olie Sylvester on his OomPaul podcast. You can definitely hear he's from southside Chicago and sounds like a really nice, down to earth guy.
