Rapira Platinum Lux, currently my favorite in the more efficient razors
Pol-Silver in my Gillette NEW(s)
KAI in my Gillette Slim & BB
Nacet in Rocky (6S) and runner up in NEW models
Voskhod for a smooth shave in anything, although not the sharpest
1. US Personna/Accutec Lab Blue
2. Astra SS
3. Anything else from PPI, except Nacets (Nacets work fine for me, but the 100 pack that I have rust after a single use).
4. Treet Dura Sharp PTFE-coated carbon steel blades - smooth and forgiving but go for 4 shaves before rusting.
5. Treet Black Beauty blued carbon steel blades - smooth and forgiving but rust quickly.
I have four, sorry, not five blades that are “top” for me. I have tried many, and will keep testing others, but four have earned “top” rating for me, and are in my rotation. In no particular order: FEATHER, PERMA-SHARP, Personna Platinum, and PAA Strangelet. I like choosing which blade seems right - and fun - on any particular day.
