Gentlemen,

For a time, I had a running battle with the Feather DE blade: more than any other blade, it shaved smoothly in one razor and ate my skin in another. In the end, I discovered the Feather to be the most eccentric of all the blades I used.

The Feather is smooth in my Timeless CC and OC razors, as well as the Charcoal. It did well in the iKon Shavecraft 1 and 2, which I no longer have. Interestingly enough, both Polsiver and Gillette yellow bombed in the Timeless. Once gone, I'll retire the two permanently. For the ATT R1, I find the Astra a perfect fit, although I have not tried the Feather in it yet.

I use the Feather DE blade for only two shaves, as I find it gets rough on the third. For that reason, I usually have a huge supply on hand — I just ordered 200 more.

For the single edge, my blade of choice is Feather Professional.
