I've used one blade so far for three different days and in three different razors. First in a Gillette Tech, next in a Yaqi DLC Classic Brass, and lastly in an Edwin Jagger DE89. I found it to be plenty sharp, maybe on par with a Gillette Yellow ,but I think it really excelled in smoothness. For me it's not top tier, but it is above average.

Love these new blades. I have six shaves on my first blade and is still sharp. Very smooth also

This came out so very well done great job love it thanks stan

I saw all the reviews and YouTube videos on these blades. I saw Matt opening his first shipment on YouTube. So I ordered. And they did not disappoint. Very sharp and smooth. I had no irritation. I'm very happy with the purchase. One of my top blades if not the top one. And the packaging is super cool. It matches my Rex Ambassador perfect. On a side note, I turned my Rex down to just over 2.5 instead of 3 because these are a aggressive but smooth blade. Buy some you won't be disappointed.
