Happy New year to you! What you have there is a pre-colored clay pipe with either a plastic or vulcanite stem probably made in Germany. The spiky club style of pipe shows up both in the style of carved meerschaum pipes as well as clay pipes and fragments of the same frequently surface if you are an active privy digger or Victorian dump excavator. The style was modeled on a popular form of walking stick that was common in the countryside with farmers and those who fancied themselves as country folks. In terms of clay pipes you have something you can clean as you would any other pipe but it certainly would not withstand being chucked into burning hearth embers to clean out any old tobacco residue.
To achieve that form of cleaning you need one of these types of clay pipes as shown above. You have one advantage with your current pipe in that as the mouth piece is not made of clay you will not suffer from 'pipe notches' on your teeth, something that I have quite a few of from years of clay pipe smoking. Just remember the spikes on the pipe are not just for affectation. These pipes get very hot and those spikes are there so that you don't burn your finger prints of your digits. As an after thought was this one of Pipes & Cigars German imports or did you just stumble across it somewhere else?
