King Gillette prosecuted all his competitors that tried to evade his patent for the safe razor. Sometimes he should buy some of them. But the problem was that the term of his patent was ending.
It was quite possible that after the Gillette's patent term would end, a lot of new safety razors made by different manufacturers would appear.
It is known that King Gillette solved this problem. In 6 months to the deadline of his patent, he invented a new model of Gillette razor with a price of only 1 dollar. The previous one was about 5 dollars. It was the Gillette's victory and the profit that year held a record.
Thus, King Gillette, who always dreamed to change a world, changed it in its own way. He turned a shaving to a simple procedure and set the beginning of the whole branch of disposable products.
Before he died, Gillette Company was merged with its main competitor. It increased till the World War II and made a lot of innovations. Due Gillette Company, disposable razors with plastic case became popular. Now, it is possible to throw them entirely after use, not only a blade.
