Fighter/thief backstabbng question

[Stilgar]

Can a fighter/Thief backstabb when he's dual-whielding?
And do both weapons backstab or only you're main?

[Meerlight]

Fighter/thieves can backstab while dual wielding. The weapon he backstabs with is the first weapon that hits, usually main hand weapon.

Can i backstab with all weapons or only the one's used by thiefs?
And i so what about use any item?
Would it then be possible to backstab with a warhammer or something?

[Christian]

Only thief weapons, sorry...

It's weird, because you can backstab with a club, but not with a hammer. It seems like you should be able to use a hammer, though...there's even that song "Maxwell's Silver Hammer".
