a weapon i drew up in this largely representative form in fire alpaca
more to convey the design than to outright be the perfect render of it

a bone and black iron scythe with a blade of underworld flint and spikes of ice, the weapon can shapeshift as shown in the pic, taking on a more offense oriented sword for fast slashes and cuts or a more defensive tonfa form which uses the thick blunt side of the blade to block attacks and relies on its ice spikes for dealing damage
