I do this all the time. With knives.

ThisTroper had his friend teach him how to play dagorhir this past summer. Being leagues ahead of me in skill, he more or less wiped the floor with me every time, except that one duel where clever feinting with a sword and axe gave me just that little extra edge. I proceeded to lose every subsequent match due to running out of smartass ideas.

This Troper's sister usually Dual Wields axes in Dagorhir, and kicks a surprising amount of ass for a post-natal housewife... then again, she is a FieryRedhead CoolBigSis.

This troper often wishes that [=ODSTs=] possessed adequate hand-eye coordination to do this during Firefight in Halo 3: ODST.

After watching a few videos on YouTube, this troper had a go at playing two saxophones at once. Soprano and alto are easier; alto and tenor are more difficult.

This troper, who dislikes {{Light Gun Game}}s developed by Midway, tends to have more fun with them when he plays both players at the same time.

This troper did this when playing a game of ping-pong at church; using two paddles at once. I called them the Blades of Chaos, if you where wondering.

This troper noticed in his {{LARP}} that dual-wielding is inordinately popular among newbies, and a sort of sideways GameBreaker; against single opponents, it can be extremely effective (especially if the opponent has a {{BFS}}, like this troper uses), while in organized group battles, it tends to be utterly useless, since you're very likely to get swiped at by people far out of your range.

Kulture here, and in my experiences it requires creativity. When I rolled akimbo short swords at a major larp event, I covered my faction's shield-wall by parrying incoming blows (raising a shield in a shield wall is notoriously difficult with latex edged shields), and even managed to blade-lock a faction leader , allowing my faction's front-liners to pagger him where he stood.

"You're just jealous because I am dual-wielding flamethrowers"

Not that badass, but this Troper almost always cooks with dual-wielded wooden spoons.

This Troper does this purely for the RuleOfCool whenever he's in a play fight. No matter what the object is - toy swords, Legos fashioned in the form of swords, any kind of ball that won't cause physical harm, video game controllers, books - if it's in reach and can be dual-wielded, I'm probably dual-wielding it. (Note: Dual-wielding ''always'' puts you at an advantage if neither of the participating have formal weapons training.)

This troper tried DualWielding two Wii remotes to beat SinAndPunishment2's final boss's final phase. one where you have to protect Kachi's soul.. It actually does not work better than using just one.

Once in a science class fight, I decided to go one step further and triple wield metre rulers, versus a classmate who merely held a stack of rulers in one hand. It was awesome.

No formal training beyond watching a crapton of anime, but I've trained both myself and my younger brother(who is surprisingly skilled for a six year old...he uses that size to his advantage) to swordfight. I taught him basic tactics, and allowed him to develop his own style. We currently differ, as he uses a full blown broomstick(I don't let him near the actual models...), and I counter with my shorter, nodachi-sized weapons. Very simple tactic, though effective, really. Parry, thrust. Win.

After playing too much FinalFantasyIII and KingdomHearts, this troper always likes putting 2 of anything in each hand and imagine that he is dual-wielding them. ANYTHING. Among the things I've dual-wielded are:

Newspapers

TV remotes

Pens

Books

Jugs of milk

Dumbells

Nintendo DS styluses

ThisTroper once had to dual-wield ''calculators'' for an exam - a financial calculator, and a plain scientific calculator that had the useful multi-row display. No, it does not allow you to save time by answering multiple questions at once, don't try. It does, however, allow you to use alternate forms of a calculation formula at the same time, provided you're relaxed and clear enough to do so.
