Scott's Magic "mini jacks" can be used to ream open the smallest opening using one of the triangle shaped blades and moving in and out of the flame. Use the outward force of the beveled edge jack blades for opening any 2" or smaller tube or encalmo section for a nice, even wall and cup shape. Other great uses for the "mini jacks" are finishing of hollow beads, pendant loops, fine tuning a mouth piece or raised carb, or even opening the construction of a down stem. The mini jacks are made of hardened stainless steel. The jacks can be held directly in the flame for a few seconds without damage to the steel. Although the ideal use of the jacks is with the glass in between the tool and flame and in many cases the shaping is done just outside of the flame. The dimensions of this awesome tool are 8.5" long and the blades are .5mm at top to 12mm at widest edge. The flare dimension range is 1mm to 55mm.
