Mario (Super Mario RPG): Hammer, Glove, Turtle Shell (if I remember correctly)

Ness (Ninten and Lucas too?) (Earthbound) : Yo yo, bats

McDhol (Suikoden) staff
Riou (Suikoden 2) Twin Fang
The Prince (Suikoden 5) Nunchaku

Yuri: (Shadow Hearts) Knuckles

I'm sure I know of more of them, but I can't remember them right now =|

EDIT: Now I remember some of them!
Mag Launcher (Evolution) Hand cyframe
Pokemon Trainer: Pokemons
Eve (Parasite Eve) Guns and clubs

Shu, Jiro, Kluke, Marumaro (Blue Dragon): Shadows

Rudy" (Wild Arms ALter Code F) ARMs (in alter code, he only uses knife when out of bullets, I think)

Goemon! (Mystical Ninja) Pipe

Suikoden 2: unnamed dude. Uses double tonfas. Quite a badass weapon for a main character, I gotta admit ^^ whoever thought that up is a genius. Actually, whoever thought the whole Suikoden 2 game is a genius.

Suikoden 2 rules! And so does tonfas.
And I did mentioned him. I'm just accustomed to typing Riou as his name thanks to suikosorce.com

Polka - Eternal Sonata (umbrella)

Will from Illusion of Gaia uses, of all things, his flute.

Mint from Threads of Fate. Used some rings that were more casting magic than striking. I couldn't tell if they were "bladed" or not... but assuming how little damage they did, I'd assume they were just dull golden rings.

Rhapsody: A Musical Adventure- Cornet Espoire: She uses a horn in battle.

Prier from La Pucelle Tactics. Her only weapon of choice was a batton.

Heh, Megaman. The original Blue Bomber: everything but swords!

Well, some of his weapons involved blades... like cut-man, for example. Also, megaman isn't traditionally an RPG character. Megaman X: Command Mission was the only RPG I know of... but at least in that game he, in fact, did not have any form of bladed weaponry.

Oh here's one. The protagonist from Nocturne. Fistycuffs all the way.

Ohhh dur. I should have thought of this along with Cornet.

Marona from Phantom Brave. She just controls phantoms, she really doesn't wield any particular weapon by default if I remember correctly.

.... Screw Nocturne. ^_^

(Just saying that to get you riled up, Lantis.)



.... Okay, there's Fei and Shion Uzuki from the Xenogears/Xenosaga/whatever-name-is-official series.

no... screw YOU!

*makes prunie face*

What about that blue haired guy from Quest 64? Didn't he use a wooden staff the entire game?
