Rockwell 雙刃刮鬍刀片

I’ve been using one blade for over a week and it’s still smooth on the third shave, so the 4-8 shave estimate feels right. At 100 blades, that’s basically two years of mornings sorted for the price of a few cartridges.

Got through my first blade and it still felt sharp on shave number seven, so the 4-8 shave estimate holds up for me. The 100-pack is a solid two-year stash that I don't have to think about again.

Shaved three times a week and these blades hold up for a full week before I notice any tugging, so the 100-pack should genuinely stretch to two years. The sharpness on the first shave is noticeably better than the random drugstore blades I used before.
