i've never tried Feathers..but the Polsilver Super Iridium along with the Gillette 7'oClock SharpEdge & voskhod Teflon Coated, are my favourite russian made blades..all imho superb blades, which give excellent results.Especially the Polsilver Super Iridium. super sharp,super smooth.
Here's something i posted yesterday on razor burn.my humble limited advice on aggressive & non-aggressive razors and blades.
we all get slightly overzealous with ourselves sometimes ,and forget the vital basic DE shaving rules.. shaving Angles with DE razors - Use a steep angle with more aggressive razors or sharper, less-forgiving blades Use the shallow angle with milder razors/blades. Whichever angle you use, do NOT press onto the face with the razor - Just let the razors weight do the work and you'll be fine!..i've trained my mind to shave the lather from my face,rather than the stubble.
This post doesn't mean to be patronizing in anyway,..i've learn't to use my more aggressive razors with this method, with no irrtation, nicks or cuts..i hope this helps in some way.Regards.
