Nicks, cuts, razor burn, and all that money spent on blade after blade. Why on earth do we shave - is it all for the sake of vanity? Man began shaving more than 30,000 years ago with rocks, for razors. Today, razors rank among the sharpest tools ever created. “A razor blade can actually shear the atomic bonds in a piece of hair..” . And to give that razor sharp edge a gentler touch: “A lathering cream gives a very nice cushioning for the blade, so you get very nice lubricated shaving…” . So sit back, and enjoy. Your morning shave is a testament to the science, soldiers, a few madmen, and billions of dollars in technology that have made shaving with rocks, a horror of the past. An interesting look into the science involved in the research to create the ultimate razor.
