Review on 🪒 20 KAI Cutlery Stainless Steel Double Edge Razor Blades: Premium Quality for a Smooth Shave by Marianne Green

Very sharp but smooth unlike Feather blades which are very sharp but not as smooth. This is the best I've found for my vintage 1955 Gillette Tech and Super Speed. Update: They also work really well with a Feather Popular (very soft) razor and my Gillette Slim vintage adjustable razor set at #3 (one setting less than what I normally use). For moderately aggressive Merkur 34c and 23c razors, Gillette Silver Blues, Polsilvers, and Astras are just as good (and cheaper), but for soft razors like Vintage Gillettes, the extra sharpness is important.
