I use this

Just got it 2 months ago. The blades are ULTRA ULTRA sharp. I have cut myself several times with it. However, it gives me a super close shave, that is unmatched with anything else.
Does anybody know of any other blades that could fit into this because frankly I think the feather ones are too sharp and I don't like walking around looking like I got into a fight with a cat somedays.
