I have that little blade bank as well, but I only use it for DE blades... I put the used AC blades in the bulk blade packages in which they come. I don't want to assume anything, so there is a slot at the bottom of the package for inserting spent blades, just in case it didn't come to your attention.Hey, does anyone have the Mühle Blade Bank and could tell me whether it's also useful for the disposal of AC-style blades? Or are they too long?
