Pipskicks was kind enough to send me some yellow 7 O'clock blades. I've used 1 blade for 3 shaves now and I have to say all 3 shaves were great. I usually toss out my blade after 3 shaves no matter what. However, after today's shave, the blade still seemed as sharp as the first shave so I'm going to see how many shaves I can get out of a single blade. Depending on results, this could replace ASTRA SP as my go to blade.
