Going on the picture..that looks like whats called a 'bastard sword'..long enough in the grip to be used two handed..but mainly meant to be used single handed..also blade style is designed to be used against armour..stiff, diamond section for punching hrough plate..not really a cutting weapon..real life weight..prob no more than 5-6 lbs on average. My money..the Troll being relatively lightly armoured..he'll prob move faster and that mace would crush that armour :)
