As some of you know, i'm using the feather straight razor. By all means it's sharp. But what strikes me most is the large variance in longevity. Sometimes i have a blade that will hold out for 20 or more shaves... now i have a blade that only lasted 2 shaves (and a third one i forced out of it but didn't really go that well). Seriously, what gives? am i doing something wrong? I'm already drying my blades to not led them get corroded but it just isn't that consistent as i expected.
