Yes Gentlemen swords and knives are pointy sharp nasty things and if your not careful this may happen to you

but it's only a flesh wound I had worse

On a more serious note you must always be aware that these are all live blades and whether removing them from their scabbards,cleaning the blade or just picking one up at a show one must use caution. I have seen idiots picking up a swords at a show and waving it into the isle.
