The last stinger in a new pipe was in a BC, and it pulled right out. I don't find they help, and sometimes
they clog or impede the draw. Of course, with a Kaywoodie drinkless, I'm stuck with the stinger that also
screws the stem to the shank; be advised Kaywoodie makes good, new pipes that don't have this feature,
the Saxon among others with a push bit. I kept the stinger out of my BC, in case I wanted to sell the pipe
later, but that possibility is remote. It's a great blast billiard up-market pipe bought on sale, new at an estate
price.
