Lay the removable pointed tip of your soldering iron on a flat surface. Use the hammer to pound the tip flat. The metal should flatten easily. Be sure not to flatten the point where the tip reattaches to the solderer.

Wet the knife sharpening stone and slide it on the edge of your flattened tip, back and forth across its surface. This will create a a sharper, angled surface, which will improve the speed and accuracy with which the hot knife cuts your wax.

Use the knife to cut, shape or sculpt your candles and wax pieces. When you are finished working, touch your hot knife, while it is still hot and plugged in, to a paper bag. The paper bag will absorb any wax that remains on your hot knife and make it clean and ready for the next use. Unplug and allow to cool completely before storing.
