METAL STEM & Screw thro bowl |
| The bowl retaining screw on my example appears to be a Kirsten screw, but since the smoke is drawn through the smaller hole , on the smokers side of the "plunger", just about any screw will suffice. The "plunger", very similar idea to that of the Spiral Kool/Aero Kool, acts as smoke tube, tar filter and stem cleaner all in one. |
