You are a joke .A Viking Age Sword weighted between 1 to 1.5 Kilograms , a 2-Handed Axe from that same time period weighted between 1 to 2 Kilograms ( Or less ) and a Claymore weighted around 2.5 ( And this is just a heavy Sword ) .If you tried to use a heavy Weapon , your opponent would just kill you before you could even move .More weight also means more mass and more mass means less space to use it and more chances for the hilt to shatter into a 1000 pieces .Go read a Book or try to practice an actual Martial Art .
