1.4.4.2. Single-edged Weapons must have their non-striking edge clearly marked for at least 12 inches (30 cm) with tape, paint, fabric, or other material in a way that clearly contrasts with the striking surface cover and does not wrap onto the flat of the blade.
The whole rule book doesn't say much about edge of weapons. I use cylindrical weapons, so they don't really have an edge. What should I do?
* thank you. I wasn't sure if all weapons were supposed to have an edge or something.
