yep, in
this picture you can see a little golden eagle head of the sword next to his left hand axe head. it was the only picture on Forge World where the sword is visible in any identifiable way.
there's
another picture that I think has a picture of a black sheath but I would think Angron would use a beat stick rather that that tiny sword. how about give it to a worthy Chaos or Legion Lord instead? haha, no. we can't have an incomplete Primarch model.
