I've used the Treet carbon blades for about two months now. They have a different sound and feel in my Leaf Twig razor and require different pressure and speed compared to the Personna Red, which is the standard blade I use. I am getting 2-3 shaves out of the Treet versus 3 out of the Personna Red. It is easier to avoid razor burn and the occasional cut with the Treet carbon blades. The Treet blades have a coating of some sort on them versus the 1940's and earlier carbon steel blades. Even living in the Pacific Northwet near the Sound, the blades are not rusting in the 2-3 days that one lasts. For the money, these shave close and smooth.

1 and done for this blade. Wasn't very sharp at all, quite tuggy actually. No irritation, just didnt cut worth a crap.

I absolutely love these carbon steel blades, these blades provide a very smooth and comfortable shave with very minimal irritation if any at all. I got 4 very comfortable and smooth shaves with only 2 passes. I don't wipes these blades, however I do Pat them down with paper towel to dry them.

I really like these blades. They deliver a very smooth and easy shave with no irritation. They leave my face glassy smooth. I air dry these blades after use, I don't wipe them down basically because it says not to on the package. I've had no problems with rust and I'm getting 4 nice shaves from them. I highly recommend these cool looking blades!
