I've been working through a blade sampler and recently tried a Shark Super Chrome. Since the Shark Super Steel has become one of my favorites, I wanted to see how these would do. After 2 shaves, I'm slightly disappointed. It seems less sharp than the SS albeit just as smooth. Maybe slightly more so. But the differences seem minor or even illusory. In that case, the SS are a real bargain at under 10 bux per hundred delivered. No need to spend more on the Chrome, which reminds me of a Derby. I can't really vouch for longevity as I toss all my blades after three uses. Two if they start to tug.
