Okay Pro's, I have found myself smoking my Estate Medico Cavalier lately and I find I really like the feel if the bit in my teeth. I am a clencher and this bit shows virtually no signs of wear or teeth marks. Can anyone tell me what this material is. I am guessing acrylic but I am pretty new to the world of pipes other than my trusty MM Cobs. I wouls like to get this type of stem/bit for a few of my cobs so I quit chewing through them.
