Yes. It's true. Review by Mike
Well guys and girls, It's true. These blades are very, very sharp. In my opinion this can be a double-edged blade (excuse the pun). The first time I used the Feather blade I cut myself all over. The next time, not so much. Of course, now I use them with focus and achieve a very close shave.
Very Sharp, High Quality Blades Review by Paul
These are some of the best out there in my opinion. Go slow and pay attention to what you are doing with these. You will get an extremely close shave.

amazin cutting Review by JR
These blades are so sharp, so smooth, so effective at cutting through my beard. Just to double check, after about 2 weeks using the Feather blades, I tried another Derby blade to see if I could get comparable results. I simply couldn't. After 2 or 3 dragging, tugging, pulling cuts with a (new) Derby blade, I put back in the Feather and may never use another brand of blades again.
Stay sharp. Review by bnr
By far the sharpest of the blades I've tried, the Feather will give a startlingly close shave. As the other users have pointed out, that sharpness is double-edged: you must pay attention to what you are doing, and you cannot hurry too much. Careless dragging of this blade will leave your face looking like a crime scene. A careful shave will produce a delightfully smooth cheek.
