I was looking to add this premise of a weapon for a character I'm writing. I remembered this style existed in Breath of the Wild as an Eightfold Blade. While it does have a hilt, it is only a very small circular guard with no ricasso. The main thing that I'm focusing on is the name of swords that have the little hook mini-blade near the hilt, similar to a hook sword in strategy yet more simplified.
At first, I thought the hook was a Schilden, but Schilden tend to have their tips pointing perpendicular to the blade (below), and not like the Eightfold Blade in the picture.
Is there any historical name for this type of sword, or is it just fantasy? If so, what is the closest historical classification?
