PLEASE READ: Yes, I know guns are better than melees. But Im just curious to know what the best melees are.

1) What is the best melee that I can buy with gralats?
2) What is the best melee i can get without event coins (like in a trade)?

Each melee must do at least 8 damage and preferably be fast. Im thinking Captain Morgan's Golden Sword is the best I can buy with gralats, but I dont know for sure.
