Good point about the distinction between woodworker and pipemaker.The main issue is tha some wood worker, not pipe maker, made a pipe out of that piece and decided to blast it in order to cover the flaw.
Although these pieces look very very nice in some cases, I've often wondered about the build quality and smoking characteristics - not really enough to buy one and investigate though! 8O
The seller has a similar pipe up for sale again this week,
Yuan Fei's pipe,---- unsmoked
There are a variety of different names used for the "brands", Huge Stone being one that I thought was pretty funny, many of the pipes are direct copies of the famous makers, I can understand how they might be tempting, and sometimes sell for $150+
Here's a yummy video I found!
