Yep. A standard DE blade is 22.0mm wide, whereas a Kai blade is 22.2mm wide (i.e. an extra 0.1mm [or blade thickness] each side. ShaveWiki Reference Link.I've heard that Kai blades are marginally wider than other blade brands, so perhaps this is having an impact on the feel of the blade. Some people apparently use them on razors that they wish had more blade exposure. I don't have experience with either brand of blade, so this is just what I have picked up from various forums!
