So basically that iron whip is just a even more brutal police baton and looks like it crack skulls open easily. @Tych
Just think of it as a even more brutal police baton.
In past, whip has many forms, but this is the 1st time I saw Iron Whip in non-rope type. More like a steel forged baton and it considered as lethal blunt weapon due weight and force it generated easily crush your skull like smashing a cookie.
@Tych Another (western?) name for it is swordbreaker. I think it's supposed to have a pointy end, so you can thrust with it like it was a sword but otherwise it's more like a mace.
@sinisempi Does look like a mace. European swordbreakers' look the part more tho imo. Don't know if those notches in the rod actually help break swords as much as smacking a sword really hard till it snaps.
