It could be that Savinelli relegated these pieces of briar to the secondary maker due to poor quality. I'm surprised you discovered these small holes! Do they affect your ability to smoke the pipes? If so, one solution may be to use something like a miniwax blend-fil pencil, which is used by craftsmen to fill in small scratches and imperfections in wood. Here's a link:

However, if this is happening to many of your pipes, perhaps you should invest in one with really thick walls!
I can see many of us on this forum trying to blow bubbles with their pipes now! It's the new "washing pipes with hot water in the kitchen sink" debate! :rofl:
