Polsilver Super Iridium Double Edge Safety Razor Blades, 10 blades (5x2)

Love them. They are sharp but smooth. I get a nice shave with these blades and my iKon X3 slant. I get about 4 shaves out of them and I shave my head and have a go-tee. For a reference...... Feather blades irritate my skin and want to bite, but Astra and Gillette 7o'clock and silver blue work good for me. These Polsilver are smoother than those other blades for me.

Sofar I used one blade. During the first shave it looked not as sharp as Astra. But I had 7 very comfortable shaves out of it. For comparisonAstra - 2-3Gillette Silver - 3-4I definitely will by a hundred of them.I use Mercur 23c and Burt's Bees shave cream.

These are my new favorite, replacing my old Remington feathers. These seem to be a bit sharper and last longer. My beard is pretty thick so I like I can get a couple shaves before pulling starts.

Excellent blades. Sharp and smooth. Just what you need for a great shave.

I consider the "Feather brand" the "gold standard" of double edge safety razors. These run a pretty close second.

great close shave

These are fine blades.No nicks and they provided an even shave. I have a coarse beard, so they did not last as long as others (Feathers).

These are well made but don't match well for me. I have a tough beard with somewhat sensitive skin & these blades are slightly too aggressive for me.
