Review: A happy face! - Different razors for different faces and all that...but for me these razors are worth every penny. I'm comparing to Astra Platinum, Gillette Silver Blue, Gillette Platinum, Feather, Persona Med Prep, and Merkur. I have sensitive skin and a very coarse heavy beard. I've being trying for decades to escape lingering razor rash (cartridges, Norelco, Panasonic, all kinds of creams and aftershaves). So why Kai? 1) They leave no irritation, rash, or razor burn even in daily use (only other with no irritation is Silver Blue) 2) They shave closer than anything else, especially in tricky places. Simply the closest shave I have ever enjoyed. 3) They are consistently excellent blade to blade -- no quality control issues or variance 4) They are just beautifully honed, high quality, stainless steel. No coatings or PTFE to wear away and, in the latter case, that accumulate in organisms throughout the world with unknown effects 5) They last twice as many shaves while staying sharp and still shaving closer than anything else without irritation! I can get 8 shaves out of them easily. They are not the most comfortable while actually shaving -- they are not uncomfortable -- but some, like the Astra feel smoother while shaving and then leave a nasty rash afterwards (and don't shave as close). Sure, the Kai are twice the price of others, but since they last twice as long and shave better they are actually a great value. Just for the pleasure of having no rash, they are worth it. Highly recommended to try.
Review: My favorite bades - These are the best, most sharp blades I’ve found. I prefer them to feather because of their thinness and maneuverability.

Great razor blades— maybe even too sharp. But they last a long time.
