What's the Name of That Book??? discussion

All i know is they enter this world after their girl-friend disappears, then they get a knife that is in a special pouch cause it cuts anything, then they meet dionysius who is having a party and travel with him to a demon city type place. It is NOT subtle knife and it has nothing to do with Percy Jackson.

Joanne, are you still looking for this book?

This could be 'The Homeward Bounders' by Diana Wynne Jones. The knife is actually a girl's arm, which she can make into anything by concentrating. There is a place they visit where everybody is perpetually tipsy, from drinking something called 'creema de leema'.

Sounds like 'Fear the Fantastic' (book 6 of the Everworld series by KA Applegate). 3 boys and a girl enter a parallel universe, the books are about their adventures while searching for their missing friend. They have a pocket knife made of special steel that cuts everything and in this book they join up with Dionysus and travel to the city of the main antagonist.
