My husband, in a moment of insanity, made a couple of 8 inch swords out of wood for our son and daughter. Our son, who was 3 at the time, carried it with him everywhere -- including into Wal-mart where he caught his sister unaware (and without her sword). Unfortunately she's prone to nose bleeds... Staff members came running and offered ice packs as she bled on the merchandise I hadn't yet bought (and then spent the night scrubbing).
In my husband's defense, he did end up making a shield, but only one... which he then gave to our son who wasn't the one requiring protection. And it was cardboard. You all know how rock, paper, scissors works, right? Well along those same lines -- wood clearly beats cardboard.
I hide the swords whenever they surface in the hopes of preventing further spilled blood... But, every so often the kids get a few moments of fun before I notice.
