There is a tendency to assume that we should be generating a single standard for fencing at our living history events. In fact, we could talk about distinguishing different levels of authenticity and safety appropriate to different contexts, since a single set of customs could allow for them all. As regards authenticity, it is inappropriate for us to allow obvious visual inauthenticity when the public is watching. We can wear cups underneath our breeches and no visitor need by any the wiser, but if we use modem foils or helmets, we are giving people a very false picture of the past. As regards safety, different people have different expectations.
Nobody is prepared to venture life and limb.
Some people are not willing to take anything more than a minor bruise. If this meant that fights had to be choreographed, so be it. However, my own experience suggests that it is possible to re-create fencing authentically and safely without choreography. We cannot re-create duelling. We like to engage in mock-fights with rapiers for fun and physical discipline.
