Depends on the razor you use
EDIT - These were highly dependent on the razor for me.  I started using them in my Parker Variant and they are excellent in there.  I hated them though in my Merkur slant and my vintage Gillette flare tip.<br /><br />These blades were terrible for me.  I’ve used several blades and these are the worst so far.  Caused all kinds of irritation and didn’t seem all that sharp either.  I tried them in two razors just to make sure it wasn’t the razor.<br /><br />I had thought these were the “Israeli reds” that I’ve heard so many great things about but they were terrible for me.
