The walls are thinner any of the other pipes I have except maybe the Stanwell Golden Danish on the right (on the far left in the pic with the 3 pipes). It does concern me, but I do not know the strength of briar wood. Please look at the photos and tell me what you think. The diameter of the shank is identical to the golden Danish (brown), however the Johs (newer .. on left-orange) has a bigger bowl. I also used a penny in the other shot as reference, along with a third pic showing 3 pipes (Golden Danish far left, Johs-middle, another stanwell-far right) .. again for reference.
The thickness of the walls seems very close to the Golden Danish, but the structure is different (the GD rounds out on the bottom which would, maybe, provide more strength to the shank).
Anyway, if it were bamboo I would not be concerned.. but I do not know the physical properties of briar and so I wonder if this is a shank that will last.
I really like this pipe. It is so well balanced .. it is absolutely the best Johs I have ever handled. I just wish the shank were a bit thicker. Though I do know why it isn't .. it is because of the balance. It is a sitter .. and it is so precise that if you take the stem off ... it tips (the stem can't weigh more than a gram or two. I just hope they didn't sacrifice strength for balance.
OK, now that you all know I'm obsessed with details ... (sure why not ... call it OCD if it helps) I would greatly appreciate opinions.
