One of the highest innovative designs that the company Callaway came up with was to design a abstinent steel driver that had a critical and supplemental forgiving head than any previous draft. The CEO, Callaway dubbed it as 'Big Bertha' which was derived from a German cannon back in WWI which was famous for its power of shooting long distance range. This manufacturer of design was the one that made Callaway golf club a house hold name in the states because it realized millions of sales and the Big Bertha type of Callaway golf club was the reason why Callaway became the number one manufacturer of golf clubs not hardly in the US but in the whole world which shows how classless golf is to the whole planet.
