The Shark Super Chrome blade has done well on its first two outings. Yesterday it tackled 34 hours of whisker growth with ease, giving a nice result. Today I did a simple one and done shave since I shaved mid-afternoon and will shave again 15 hours from now for work tomorrow. So far, I think it's a decent blade. I plan to use it 2 or 3 more times before trying another from my "assorted" sample stash of blades!
