I just received my "Einstein" pipe from Boswell's Pipes. J.M. calls it a "nose warmer." It smokes like a champ with some of J.M.'s "Pom Holiday" aro, which was a gift ounce from the company.
Honest, I have no stock in Boswell's, but if you haven't tried dealing with them, you are missing something in the pipe hobby. They have wonderful pipes, great tobacco, at the right price for both.
The Einstein is a bent 4 5/8 in length. Is practically weightless. Has a beautiful briar finish and the bowl is deep enough for a hour-long smoke.
And, it looks exactly like one Einstein was smoking in one of his photos taken while he was contemplating the world.
Did I say I love this pipe!
