I'm referring to my ikon oc 2013 model. I just love this razor. It takes off 2-3 days growth like nothing. I was under the impression they are very aggressive by nature. My R41 is on the other end of the spectrum. I find this razor to be less aggressive than my slant, witch I don't find to be aggressive. I've been using a gillette yellow in my oc and also feathers. Both blades work very well.Highly recommend this razor, can't wait for the slant to come out.
