...I'm hoping you mean what I think you mean, or this is going to be very awkward.
Any blades, but I only have one sword a larger collection of daggers. My favorite would be the kris that was my first. It's reeeeally pretty, all black with a pretty carved hilt. That or a bodice knife who's pommel has a dragon clutching a most likely cheap jewel but is still fairly neat to behold. Or in general I like kris blades, although there's a special place in my heart for broad swords because I grew up on the Highlander movie. How about you?
