So I just shaved with these blades just the other day as i shave every second day to reduce irritation on my face (it gets itchy sometimes with these hot summer days. My previous baldes were Geather and the Voskhod. The Feather blades are the sharpest I have used. The Voskhod feel as though they just glide acrossy skin- so smooth, but they are not as sharp. These blades (Persoonna X) I would describe as a mix of the Voskhod and the Feather. I took one pass each of against, across to the left, and across to the right of the grain to get super smooth (even against the grain on my neck and my neck usually gets itchy really easily). The thing about the shave is that I never felt as though I would cut myself or the blade was scraping my face, it was just smoothly cutting my beard. Even after the three passes mentioned above, my skin felt great and smooth. And I shaved without shaving cream or soap. I simply warmed up my beard with warm water and shaved. It was that smooth. I didn't even feel any burning after i splashed on my after shave. Really recommend these blades to anyone that wants something sharp and super smooth.
