Yes, I compared the Russian KCG vs Chinese KCG over about 12 shaves. The Chinese KCG is very sharp but not as smooth as the Russian blade and doesn't last as long as the Russian blade. The Chinese KCG is a good blade - as long as you aren't comparing it to the Russian KCG which is an excellent blade.
Thank you. It is disapointing considering how good the Russian KCG were. For me the best gillette blade, only sold for a short amount of time at a price that discouraged people to try it.
