Nacets because these are soo good!
My only 100-blade purchase has been Personna blue because (1) they were cheap and (2) they weren't made in Russia or China. They're adequate blades, but I probably won't buy them again.
My next 100-blade purchases will likely be Kai and Feather because (1) they're the best blades I've ever used and (2) they aren't made in Russia or China.
Interesting you mentioned 'smooth'.100 Kai purchased today because they're super smooth, sharp, and last me at least 12 shaves per blade.
