The blade does go slimmer as it goes up towards the top (the above screen shots dont really show that well) 
Sword 01 in the pack is doubled handed and stylized as the mentioned and very big, aimed at a boss or medium/big player character with loads of stamina. The handle is also chunky so i designed that blade to be chunky at the bottom to fit in. But yeh your right it can be scaled separately if needed i guess
Thanks for your feedback mate, sometimes when you work on assets for such along time one tends to miss these things
