The Senior Pipe Reamer is a precision tool designed to remove and maintain a suitable layer of cake within a pipes tobacco chamber. I’m pretty sure if you have been smoking pipes for a while you’ll have considered adding one of these to your arsenal? Same here to be honest. I’ve pretty much used a knife in the past and while it does a good job, you have to be mindful of gouging the chamber out of round. Also cake can be quite delicate in places and its all to easy to get carried away and remove way too much or equally bad produce an inconsistent cake depth (thicker one side than the other).
