I’ve never seen such a multitude of different tenon styles until I started looking for a second meerschaum pipe. I have an altinay that is a standard push pull tenon. There is a language barrier between me and the carver here so he’s just been sending my pictures of the tenons on his pipes. Most are clearly push pull but this one stumped me. It’s not a twist tenon but I can’t tell if it’s quite push pull. Does anyone have experience with a tenon like this on their meerschaum pipe?
