Kharn(Gorechild)

I picked up the Kharn the Betrayer model yesterday and love the model overall. Originally I'd wanted to chop him apart and make him a bit bigger but looking at the detail on him I really don't want to any more. That said, know that his axe, Gorechild, once belonged to Angron(Primarch of the World Eaters) I've come to the conclusion that the axe, which is barely big enough for Kharn, isn't nearly worthy of a Primarch. Below is a picture of Kharn as he is and one of the images of him in which it shows that his axe is quite a bit larger than the model... anyway what I'm wondering if anyone know's of a kit/bit that I could use to make his axe large enough to befit the champion of Khorne and his former Primarch.





Sorry about the size of the first pic it didn't look that big because of the white background...

Have you looked at the axes on the nobz in either AOBR, or the Nob box? Some of those 'uge choppa are just that, 'uge.

I see no kittens anywhere in any of those pictures!

There ya go, kittens... now any more suggestions on Axes? I had a look at the AoBR bits and they look a little too 'orky' for my taste.
