These are great blades they shave much better than the feather and they seem to last around two weeks of daily use so they’re great and a price is much better than buying the feather

I find the HiCarbon blades provide a smoother shave than the Feather blades, without sacrificing efficiency. I've never looked back once these blades became available!

I went all-in and purchased the Genesis a few years ago and, after a short learning curve, had the best shaves ever with the Feather blades. When Oneblade released their HiCarbon SE blades I gave them a try. I was blown away. These blades are beyond amazing. I never really understood the idea of shaving as being part of one's morning "ritual" as I've read it described in the various forums, but now I do. After 40 years of shaving and never enjoying the process I now look forward to shaving. The Genesis feels like a real, finely crafted tool in my hand and the SE blades take it over the top.

Many months ago I gave these blades a one star rating. This was somewhat unfair as I had not actually been able to have a shave with them because I could not fit them into my OneBlade razor. Since then a friend has let me borrow a spare OneBlade razor which I the UK was refered to as the Hybrid. I was able to fit these blades into this razor and I have to say, as many others have, these HiCarbon blades ar far better than the Feather ones. They give smooth shaves many more times per blade. So my rating has changed to a 5 star.

Much better than the Feather blades!!
