I have used Rapira Platinum Lux and Voshkod in the past and liked both but still went back to my Feathers and 7 O'clock blacks. Today I loaded a one of these in the Era and made a extremely enjoyable and very comfortable 4 pass shave. Normally a 3 pass shaver but since I had left over lather I pulled a fourth. The Swedes felt smooth like a Voshkod but much sharper like a Feather. The Platinum Lux are also nice sharp blades but they seemed a little harsh on the first use. Had 35 or so of the Swedes in the drawer just hadn't gotten around to trying today. Needless to say I ordered a 100 pack this afternoon.
