Definitely some type of throwing knife.
I need the knife in my profile picture identified?
Definite Ninja activity. I am 100% certain a ninja used this knife. Most likely a high priest vatican assassin warlock.
On a serious note, their are no visible markings. So I doubt you will identify it. Sorry, I certainly can't identify it.
Could be a Viper throwing or boot knife. Known as a cold weapon. Looks close to it but the Viper is indeed a much better weapon. Or possibly a ceramic throwing knife.
I would definitely think it is not a throwing knife because of the shape of the blade, the way he is holding it, and the fact that there is a throwing weapon in his right hand.
I searched for the image on the internet. I randomly went here:

Maybe that will help
