I absolutely Love these blades! They are just the right combination of sharpness, and longevity. I used to use the Merkur blades almost exclusively but these quickly became my favourite. Be careful if you have a sensitive face though. These are Seriously Sharp!!!

I find these blades to be all that I need for my every other day of shaving.

Very good blades! I perfectly agree with Shaving 101 review: if you don't have a really hard beard, kai blades are better than Feather (and better of all other blades I ever tried, too).

I would say others comments about this being more comfortable/smoother than a Feather might be correct. Although I got a really nice shave with the Kai DE blades, I don't believe it will replace my Personna Med Prep blades. The one thing I really like about theses blades as I do with my Med Preps, is that they do not use any glue/wax on the paper. Now my question is, if Personna and Kai can wrap the blades without wax, why can't the rest of them do it. Would I buy this blade again, yes I would. I would probably rate this blade #3 right behind my Med Preps and the Polsilver Platinum.
