Steve Nelson was on hand for the MCS demonstration and said:
"the weapons used in MCS are a plastic or graphite base wrapped in camping pad foam. The weapons are shaped generally like medieval swords or other weapons, but safety is the first factor, with appearance less of a concern.
The advantage, Nelson said, is that 'anyone can jump in after hearing a 10-minute rules spiel.'
That is a big difference separating MCS from the Society for Creative Anachronism, Nelson said. Because SCA places a greater emphasis on authenticity and uses wooden weapons, combatants in SCA need to invest in a full suit of armor - plate or chain mail - before fighting."
