Its a sharp blade but in starts to RUST after 2 shaves. Found out what carbon steel is all about. Will never buy it again.

These blades shave really nice, they are sharp and don’t leave that harsh feeling feathers leave after the shave occasionally. These are my favorite so far!

I recently purchased the Treet Carbon Steel blades from Razor Emporium based upon a review you guys did. To say I was surprised by how well they shaved is an understatement. I am a fan of Feather, Kai, Persona and Derby blades. I mix them up and am very happy with all of them. The Treet blade that I recently shaved with was fantastic. The question is going to be does it stay that good on shave number 2 or even 3? Overall, very surprised and very satisfied with this new blade.
