To be honest, this is the first time I’ve encountered such vociferous opposition to estate pipes. In my neck of Europe, most every pipe smoker I know partakes.
I can of course sympathize with the "ick factor", but after reaming the briar, cleaning the wood, treating the stem in Oxy and a disinfectant, then sanding and polishing it, that estate is probably more sanitary than any pipe I smoke and clean with alcohol-dipped cleaners. And this is only counting what I can do with my modest skills. A proper pipe restorer can remove the cake to bare wood, drill out the channel and neck to bare wood, and essentially make the pipe almost factory.
I will admit that I’m sensitive to certain smells, and I’ve had estates whose carbon waft has left me icked out. But there’s nothing in there that’s not in any of my new pipes, the only difference is who produced it.
I do wonder though, for the people who are squeamish, are there any exceptions? If your wife wanted to give you a bite of her food at dinner, and she took her fork, stabbed the bit and reached out to feed it to you, would you recoil in horror?
