Tigrex Great Katana

Long Sword made from Tigrex materials. Sharp blade makes mince meat of its victims.
A long sword made by a craftsman who saw the powerful claws of a Tigrex with his own eyes and tried to reproduce their force. Besides its cutting power as a blade, the sharp spikes set all along it bite into the flesh of whoever is cut, causing even more pain.
