Obviously, there is a bit of hyperbole in the title as that's a mythological beast. This is my perception of pipe "perfection" (read: really well made pipes), and it's fine that you disagree. You do realize that your statements are your own perception of that as well - not indisputable fact? And that's my point! None of us can point to a pipe that is universally hailed as "perfect." It doesn't exist. I'm pointing to a pipe that was executed extremely well, but there's plenty of room to disagree on stylistic points (like this one). I do not agree with the first statement, see below.LatakiaLover wrote: All that sounds like what YOU consider perfection (your thread title, not mine) is defined by those who create the objects being scrutinized, not mathematics. Hm.
I'd really like to hear about this undercut business from a few of the carvers you named.
This isn't a question of mathematics. Show me the formula that proves your point.

I don't follow the last statement. What would that do for our conversation?
You have the curious habit of applying objective terms to subjective standards. It would be more helpful if you said, "I don't care for the way the bowl..." (which is completely legit) Calling it an error doesn't fit for at least two reasons:LatakiaLover wrote: That's certainly true when it comes to fanciful shapes, but not when geometric lines are the shape. There is zero room for error when making those.
1. We cannot judge the intentions of the maker, only the result. (This case is slightly different: I've watched Jeff shape at least a dozen pipes, and I assure you this was not a slip of the wrist.)
2. We do not have a physical manifestation of the Platonic form of a given pipe shape. Sure, you can say "this differs from a Dunhill in that...", but so what? The implicit statement there is "Dunhill's are my favorite." Instead of that, what you need is an objective standard to compare to, or at least one that's all but universally accepted.
Chocolate ice cream is my favorite, but I don't tell people that Strawberry is an error. I would look a little silly.

By the way, I think this is a good conversation, and there's nothing wrong with disagreeing over these points.
