It shouldn't make a difference. Maybe someone told you that to try to get you to order a pack of Feather blades?? TBH, I've never tried them, but if you Google their dimensions, they are the same as the Feathers?? I know others have used them in their Colonial General razors (currently the only AC razor I have). I plan on getting a pack eventually to try out. Just my 2 cents...
