Reddit mentions of 100 Silver Blue Double Edge Razor Blades Made in Russia by 7 O'clock

Gillette is mass producing blades. They just are not marketing (though they are selling) them in the US.

You don't generally sharpen them. How long they last really depends a lot on your hair coarseness, skin sensitivity and frequency of shaving. My stepdad could probably shave with a rusty nail, he replaces his blade every couple of months. I have stupidly sensitive skin, and get about three shaves out of a blade, but that's my entire head. They've gone up slightly in price since I last ordered them, they're $18.50 on Amazon for a 100 pack, so $.19 per blade. That pack has lasted me two years shaving once or twice a week, and I still have quite a few left.

I've ordered from Amazon seller "Safety Razor Place", at $16 for 100, and the quality was fine.

Or you can buy 100 double edge blades for the same price if you learn to use a double edge razor instead of a cartridge. $10 is mostly the standard price for 100 blades but the Gillette silver blues come at a more premium price.

Muhle makes their razors out of Zamak. I'd be hard pressed to call it BIFL.

I'm going to make a quick BIFL list with short explanations on why.

*Links are my preference.

======BASIC REQUIREMENTS======

• Pre-Shave
  >Optional, depends on your face. Warm distilled water works for me.
  
  
• Shaving Cream
  >Find one that suits you. Hard soap lasts longer, creams are better for hard water.
  
  >*Proraso
  
• Razor
  > When choosing the razor, make sure it is made out of solid stainless steel. The Muhle listed (to my knowledge, is made of Zamak steel (brittle, will break if dropped several times)
  
  >I'd personally suggest a Vintage Gillette/ Feather/ Weber/ Pils/ Above the Tie/ iKon
  
  >*Weber 316L SS Razor
  
  >Technically speaking 303 steel is not as ideal as 316L
  
• Brush
  >The brush may not last a lifetime, but is well worth getting one that you enjoy. Hair types vary and cater to different faces, note the grades of badger hair in particular.
  
  >There are different sizes and a deep or normal set which should also be taken into account.
  
  > *Wipped Dog Silvertip 22mm Regular Set
  
  
• Bowl
  >I like a homemade bowl. If you're going to be using one every day, it's best to just get one that looks nice.
  
  >This is expensive, but this should give some ideas.
  
  
• Blades
  >Each razor+blade combination is different. If you have a BIFL razor, you will probably not have to retry every blade known to man.
  
  >Blade Sampler
  
  >I love my *Silver Blues
  
  
• Aftershave
  >Depends on your face and scent preferences.
  
  >I have sensitive skin and my face dries out easily so I always get *Nivea Sensitive Shave Balm

  Cartridge shaving can give fair shaves in short amounts of time.<br />
  <br />
  Wet shaving takes longer, even when you get better at it.  It can in fact be enjoyable.<br />
  <br />
  As for technique and how to: /r/wicked_edge.<br />

  TL;DR: GET A RAZOR THAT IS **SOLID STAINLESS STEEL** NOT [ZAMAK](http://www.reddit.com/r/wicked_edge/comments/20g48v/what_if_we_want_a_more_serious_longer_lasting_de/cg32pv8).

I use this double edge razor for my head. It’s not too aggressive, and does a fine job.

I prefer the Gillette Silver Blue blades.

Once you own the razor, the cost per shave can’t be beat. Look how inexpensive the blades are.

100 Silver Blue Double Edge Razor Blades

I just order off Amazon.com - the aforementioned Wish4Blades also has a merchant account on Amazon.com (Wish4Star - I assume it's the same person) that features free shipping (including to Canada) and slightly lower pricing with the current exchange (like 1$ off, not a huge deal). Recently bought this, which made it to my door intact within 5 business days or so.

Good price for gillette silver blue ATM as well http://www.amazon.com/Silver-Double-Razor-Blades-Russia/dp/B0059QF5RS/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1411282276&sr=1-1-catcorr&keywords=Gillette+silver+blue
