So I just got done smoking my Savinelli Trevi I purchased about a month ago and noticed this when I was cleaning it: I never pull out the stem until at least a couple hours after a smoke (usually leave it in until the next day to clean) so I don't think I did this. When I looked into the mortise, I noticed a bunch of knots/pits in the wood which is what I suspect did it. Heck, it may have been there all along and I didn't notice it because of the rustication. Any ideas if Savinellis have a manufacturer's warranty? I emailed the tobacco shop I purchased it from (online) to see if they have any warranties as well.
