I’m not sure why but people seem to think that Medieval Martial Gear is unbelievably heavy. I mean, I guess it makes a certain kind of sense, the equipment is after all made of metal and metal is heavy. Armour is heavy enough, though not nearly so much as most might imagine. You can feel the weight, but they myth that if you fell over in armour you couldn’t stand up again is just that. Swords though, are not very heavy at all.
About three and a half pounds. That’s it. Most swords are about a pound less. So you see, swords aren’t nearly as heavy as all that. If you stop and think about it, anything much heavier would be damn near impossible to wield effectively.
