Hellboy Artifact: Huayna's Knife

This is my submission to the Hellboy Artifact contest! It is a 1:1 scale stone knife created by Huayna, the Head Priest of the Cult of the Jaguar, to hunt and kill were-jaguars.
The knife was featured in B.P.R.D comics, most recently in Killing Grounds and The Long Death.
Carved, painted and finished in 3 hrs.
