Well, shape is a matter of what the Briar suggests along with the carver's artistic vision. The vision is his. Liking it or not is the viewer's prerogative. Now, I know we all understand the above...and I put it out there as a preface to the following comment...that the further an artist moves from what is considered traditional the more likely it is that a smaller percentage of the viewing population will embrace that design. Cases are all over and likely through all time. I've studied quite a bit of Art History and it's a significant theme.
So...while one person doesn't prefer this sort of interpretation, others do. Me...I think this is very interesting and looks like technically solid work...but I don't prefer it either. I like a more traditional approach.
I also think a 'fine checkered' treatment on a classic shape would be pleasing. It kind of calls to mind the idea of 'micro rustication' as practised by Brackner (I think that's the right spelling).
Whatever. They are cool pipes. Fun to chew on the concepts now and again. What it's all about, etc.
