What was Kay's style exactly?

Only seen him mellee from my 3 encounters, but he hits hard as hell fast as hell but it is still an exchange from both 1 v 1's. After dueling some people I think like rock n roller is far superior in melee if he would actually equip a pimp weapon instead of that lame transmute that hits for a whopping 25dmg. eek
