“Straight Razor” that were kept sharp using a leather strop was a great idea
In 1901 a revolutionary device was introduced, The disposable Razor. The concept was easy. Produce a inexpensive razor that could be thrown away. Making big money selling people the same product over and over.
At first, no one wanted to buy disposable razors. Why keep paying for something, when the razor that was being used could just be sharpened.
Then the world changed with World War I
Razor companies gave their convenient solution to enlisted men for free and the gamble paid off! By the time the war was over, we have already developed a taste for convenience. The idea of throwing away a dull blade was born.
Even though manufacturing of disposable blades has become a refined science. The price just keeps going up and up. In a world where recycling is a must, some still encourage to add billions of Razor Blades to growing land fills.
