Abilities:

• +39 Stamina
• Improves hit rating by 50 and attack power by 76.
• While the speed on this one is still a little faster than what most Shaman want, this seems to be an Enhancement Fist Weapon, as the speed is way too slow for a Rogue offhand. It's not the top of the game (there is a better Fist Weapon sitting right up in Naxx, but for players who want a Fist weapon without having to join a guild or get in a big group to do so, this baby's a good one.
• And it pairs very well (in fact, it's probably meant exactly for this) with Greed, a weapon found in heroic Culling of Stratholme. As Wowhead's commenters say, Blizzard missed a big opportunity here. They should have called the main-hand Prejudice.

How to Get It: It's a badge item, or more specifically an Emblems of Heroism item. Just like in Outland, you can get them from Heroic bosses, from the bosses in Naxxramas, or from doing the daily quests to the Heroics from Dalaran. Stack up 50 of them, and this fist weapon is yours. Of course, with the upcoming patch, there's a chance that Emblems of Heroism could be upgraded for better gear, so you might want to save them if you don't need this weapon right away. But as always, that's up to you. The patch will likely be a long way off, so if you want to go for this anyway (it does look really awesome, especially if you pair them up), I wouldn't blame you.

Getting Rid of It: Disenchants into a Dream Shard, and like most badge gear, vendors won't buy it back from you, so it's either keep it for posterity or type DELETE into the box and get rid of it.
