These blades are some of the smoothest I've ever tried. I would rank these above IP blades for smoothness. They are treated with a non-stick coating to increase smoothness. They're nice and sharp for me and seem to last 5 shaves (I usually get 3 with IP blades). The only thing I'm not crazy about is the packaging. They come individually wrapped and in packs of 5. I enjoy the blade dispensers over the individually wrapped blades. In any case, I plan to keep these in my rotation.
