Rapira Swedish Supersteel/Razorock Mission Today was my first shave with this blade. For this shave I used my RazoRock Mission head on short/light handle. The first thing I notice was that this blade isn't nearly as sharp as the Rapira Super Stainless, which is fine because I actually prefer slightly less sharp blades in the Razorock Mission head. For sharpness I would rate this blade maybe a 6/10. This blade really shines in the smoothness category though. It surprised me just how easy it was to shave with this blade. For comfort I would rate this 9/10. This was without a doubt the most comfortable shave I ever had with my Razorock Mission. I received a 2 pass DFS with touch ups. My neck and goatee area are very sensitive, and this blade handled those areas like a champ. No irritation or weepers to be found anywhere. I'm not sure how this blade would perform in my very mild Merkur 33c because that razor needs a sharper blade like an Astra SS or Rapira Super Stainless. But the combination of a Rapira Swedish Supersteel loaded in a Razorock Mission provides a magical shave !!!
