This papercraft is the Imperial Sword, a One-Handed weapon found in the game The Elder Scrolls V: Skyrim, the paper model created by RocketmanTan.The Imperial Sword serves as the primary melee weapon used by the Imperial Legion in Skyrim.
It seems to vaguely resemble the historical Roman Gladius Hispaniensis, which was the primary weapon of the Roman Legions until the 3rd Century A.D., a reference the Greco-Roman traits shown by the Empire throughout the series, especially after The Elder Scrolls III: Morrowind onwards. The Imperial symbol is carved into the hilt. The Imperial sword can typically be found wielded by most Imperial Soldiers and Hold Guards in Imperial controlled Holds. [Source: wikia]
