Hey guys, just wanted to share my experience regarding Kai blades. These are my favorite blades of all, as sharp as a Feather in my opinion, and just perfectly smooth. No burn or irritation at all and to top it all of, no glue! I only have one pack of five that I got in a sampler and I'm almost done with it, I wish these weren't so expensive (as far as DE blades go, anyways). Sadly, I'll have to stick to Astra SPs as my main blades, very cheap and my second favorite blades. Anyone else ever use Kai blades?
