A Portland, Oregon based company, Bright Light Ventures, created the Zafirro Iridium sapphire bladed razor. This razor, with a $100,000 USD price tag, is made to last forever. But, it actually needs to be sharpened approximately every 10 years.
While this may be however cool, it is absurd and a complete waste of time and resources. Maybe I wouldn't think that if the resources used were plentiful - Iridium, platinum and sapphire. I would expect this thing to be BLINGING.
A razor lasting forever is a great idea. But not at this price, or even at a fifth of this price. A quick search on amazon.com will yield disposable razors sold for $.53, and even cheaper at $.45 if you subscribe and save. At this price, you could use a new razor everyday for 90 years and still not break $15,000.
