eBay seller/Halo fan/Brute arms manufacturer smick6 is selling this nicely done replica of a Spike Grenade. It’s spiky.
smick6 used PVC, smooth-on urethane, aluminum and faux leather to make the prop. It’s 38″ long, the longest blades are 19″ end to end, and the whole thing measures 4.5 lbs. It doesn’t contain explosives, but the aluminum blades are pointy, and would probably leave a mark if thrown at you.
The only thing explosive about this grenade is it’s price: It’s on eBay right now for $150 (USD).
