As this evolution has continued, the training and techniques have become increasingly further removed from their martial roots. One driving force behind this evolution is sport fencing's award of a point to the fencer who scores the first touch with right of way; this encourages the competitors to use scoring techniques that result in a first touch in a sporting encounter but would leave them defenseless against a counterthrust, even from a mortally wounded opponent, in a duel with lethal weapons. The development of the first touch rule itself was, in turn, driven by the increasing tendency of duels to be fought to first blood rather than the death, with the result that training for a first touch could result in victory in a duel as well as a sporting encounter, even without killing or disabling the opponent.
