realize tha despite the similarity (and obviously the cross cultural contact) the daggers and swords are artifacts of diferent cultures and are used VERY differently.
The daggers patterned like the one above are Indonsesian (primarily), designed exclusivley around the thrust (the tang structure is too weak for heavy slashing), and carried as much as a status symbol/talisman as a weapon. And a good one does just feel incredible in the hand.
The sword are (again primarily) southern Filipino, and are designed to swing rather than thrust. you'll note hilt similarities to barongs (same general culture); also many of the swords are not waved (there are a bunch of different names for this.
Note that I am speaking about reasonably authenitic blades, not wavy-bladed reproductions labeled as kris daggers or swords.
