I have a hand full of junk pipes, no names and mis-matched stems to pipes. Some smoke really good and others keep my teeth from grinding. Well, today I'm in my shop making a corner cabinet, have it setting on a couple saw horses. I have my pipe in an ashtray on the workbench. Moving this heavy cabinet around, one clamp lets go. Now that piece of white oak couldn't just fall to the floor, No it has to do a twist around and go over two feet and fall on my pipe! Broke the blasted stem off flush with a piece inside the shank. Garbage can! Luckily I own some junk pipes.
