Morning! So if you aren't in the know, OneBlade released their own blades for the SE razor. Before it was just the Feather FHS-10 stainless steel which I hated. Never felt comfortable and I was about to give up on my OneBlade. I tried these and they are much better. I'm guessing you might be able to use them in other razors that use the FHS-10? Just wanted to share. Sent from my Pixel 4a using Tapatalk
