My favorite is the Rapira Platinum Lux blades, sharp, smooth, and forgiving. If the Voskhod is a good blade, the RPL is a great blade. I use them in my Rex, and Timeless 95 OC, which are both a little blade sensitive. They're a bit smoother than the Nacets, yet just as sharp.
I get excellent shaves with the Rapira Platinum Lux.Reading this reminded me that I have almost 100 RPL blades stashed away that I purchased years ago. I remember trying a few and having nice shaves but alas, so many blades - so little time. Now I want to dig those out and revisit them. Thanks for jogg'n my memory.
BIC Chrome is crazy sharp.Bic Chrome Platinum. On the second and third shave these are sharper than Feathers. Not the smoothest blade though. I probably wouldn't use them in anything more aggressive than a DE89 or a Tech.
