I have been a member of the SCA for decades. Although live steel is carried, this is typically not allowed. Demonstration of lance is right up there with the joust as a no-no.
Interesting – when I lived in Pakistan we went to the Lahore horse show where we watched hours and hours (and hours) of “tent-pegging” competitions. Comes down from when the Huns would collapse an enemy’s tent by spearing the pegs with a lance from horseback.
