Any tips on getting it through airport security?

that is NOT a decommissioned hand grenade. it’s a cheap china knockoff that is simply cast and poorly cleaned up.

I have a real one and several of those cheapie gag/novelty fakes. They dont even use those in army training.

I hate to agree with someone calling themselves fartface, but I think he is correct. However, it does not diminish the awesomeness of this at all. I totally hate the real ones. Damn near killed myself in basic with a trainer. Never was great at throwing things. Nice post.

It is not decommissioned but it is also not a Chinese knockoff. It is a practice grenade, the red paint on the spoon indicates that it was used and recovered. I would guess that the other side of it has the letters RFX cast into the body. The RF means that it was cast at Richmond Foundries and the X indicates that it is a practice grenade body.

Cool, brings back memories…

Just gotta be cool with that in public though, you could easily get hammered by “the man” just because some moron THOUGHT it was real.

Now if you put it in a vibrator and activated the motor with the audio, you’re gf would really start to appreciate your classical music collection. :)

You’d get this through airport security by wearing a TSA uniform. Duh!

This is %50 hack! Where is the documentation???
This is pretty darn sweet, but I wanna make one. The lack of build info sucks and that makes me sad.

I have that exact same type of drilled granade in my room I’ll have to try this one

I bought mine in a army navy surplus for like 2 bucks. I would think its real there was still powder residue, you could smell it in there. They also cemented the firing pin, they’re pretty heavy, could knock someone out with one lol.

Well, if you’re going to dance around on the bus to the Bee Gees with that in your hand I’d suggest “Stayin’ Alive.”

@napalm

Aren’t “how-to’s” exclusive to weekends anyway?

Posted at 10:17 pm on Sep 21st, 2009 by 3rix

i got a fake grenade mp3 player too. of course there is no mp3 player…or “fake”:)

brick, where’d you get a hand grenade?…

Posted at 5:56 am on Sep 22nd, 2009 by Taylor

Great way to invite nervous cops to shoot you. Brilliant, Darwin-award-inducing hack.

Posted at 6:53 am on Sep 22nd, 2009 by PocketBrain

@3rix Why are how-to’s only on the weekend? they should be at least one a day.

I just got one to do this with, (real deal RFX nade) What did they use to cut it up? a dremal?

Posted at 1:25 pm on Sep 24th, 2009 by napalm

I used a hack saw.

Just dropped the grenade into a bench clamp and hack sawed it open along the lines.

There’s more pics of the build process on my flickr page that’s linked off the NYCR article. The sansa was the best fit for the grenade… but rewiring the buttons on it is a giant pain. I do wonder if there’s a better choice of mp3 player.

I just noticed this made hackaday =P been busy. I’ll respond in comments for the next few days or until I’m sufficiently satisfied this is “old news”. I mean this is a 9 month old project after all.
