Start by tracing the design onto the bar of soap, etching the lines lightly into the soap with a pointed stick or the tip of a knife. Instruct your Pathfinders on knife safety before handing out the knives:
Do not draw the knife towards yourself - cut away from your body.
Pick up a knife by its handle
Be aware that folding knives can close when under pressure.
Offer a knife's handle to another person when handing it to another person.
