Natural Selection: Wii! Hand Grenade Model
This was originally intended as a knife. Million made the models/skins as such, StixNStonz just copied one model over to make it work fully as a hand grenade (knife is untouched in this install).
Dark_Soul gave StixNStonz the idea to make it a grenade and add a sound 'oh no, the strap broke!' so he did. You better be careful with this Wii "Hand Grenade!".
