I was looking for a blade to use in my Feather AS-D2 because the blades (feather) that came with it are waaay too sharp for my sensitive skin! I was gravitating towards the Gillette Nacet until I tried these. Both the Nacet and the Treet blades are equally as sharp (in my humble opinion) but the price of the Treet blades, being considerably less expensive won me over.

This is my regular blade. This blade is both sharp and smooth, and doesn't irritate my sensitive skin. I use it it a Rockwell 2C, R3. I combine with with the Antiga Barbearia De Bairro Essentials (Generics) Shaving Soap for the perfect shave! I learned of this blade from the "Double Edge Safety Razor Sample Pack - Mild

Very sharp and smooth. Doesnt give me razor burn/ bumps at all.

These are outstanding blades and are my new daily favorite. I've tried several and these are the best combination of a close shave with a little forgiveness. I like Feather, but these are excellent as well.
