They are ALOT sharper than they feel. They are ground on a 60deg angle.. and they will shave your hair if you get the angle right. There is a method of sharpening them on a piece of glass w/ some really fine grit wet/dry sand paper (1600 grit +).. I used that method and the edge is really polished now... and it will shave hair.. it's just tough due to the 60deg angle. They are really awesome heads.
