What is the best way to cut a candle in half?

The best way to cut a candle in half is to first freeze it for a few hours; this makes the wax more brittle and easier to cut. Once frozen, use a sharp knife or a wire cutter to slice through the candle evenly. Be sure to apply gentle pressure to avoid cracking the wax. After cutting, you can smooth any rough edges with a lighter or a heat source if needed.
