Earth Breaker weapon group

[KingmanHighborn]

I've noticed this weapon isn't listed in any weapon group for a fighter, or anyone able to access the weapon groups. I like this weapon for a fighter to use but RAW it can't be used for any of the weapon training bonuses. I figured it should be a at least a hammer, and probably a polearm as well.

[Ryu Kaijitsu]

it is a hammer

[Ahuru Mazda XTREME]

What book is it in? I can't find it.

[Tarantula]

Its a hammer, listed in the fighter weapon groups under ultimate equipment.

[Nefreet]

Definitely not a polearm. It doesn't have reach.

[Lincoln Hills]

It's a blowgun.

No, seriously, it's a hammer. When I look at it, I see a hammer (or rather a meat tenderizer as seen through the eyes of a crazed Japanese cartoonist). Of course, if you're not the GM of your group, our opinion is nothing compared to that of your GM. Who I'm pretty sure will say, "It's a hammer."
