Where will the battle of the razors end?
First came the original single blade razor that you threw away when it became blunt. A revolution in its own way.
Then some bright spark thought it would be a really rather clever idea to add another blade, to make the first double bladed disposable razor.
But did the competitition rest on their laurels. Not for one moment. These boys are as sharp, as well, a razor and some genius came up with the triple blade disposable.
In ten years time we will all be using razors the size of brooms with a dozen super sharp blades. Forget a close shave; one confident stroke, and half your face will come off. That's progress.
