As a rule, try to limit such displays of the weapon, and always do so only within the Encampment. The crowds around you out and about at Faire can be too unpredictable. If you're hurt, or not feeling up to par, do not tough it out. Do not carry a weapon or continue in the Re-enactment if you are not physically able to do so. This is not fair to the safety of others.
Overinflated egos get people hurt.
Drama is encouraged. Consider what you're bringing into the arena. Some weapons were designed for display, and not for battle use. Lord Jaob Stewart of Chieftain Aaron Rockwell can assist you in becoming more comfortable with the use of your weapon, or in choosing one that can withstand the abuse of the Battle Re-Enactment. Carry a targe on your person, but not in your hands if you are using a spear.
