In the 1980s, South Korea could produce submarines and battleships, but they did not possess the technology to produce nail clippers. When the upper and lower teeth are in mesh, the chink must be 0.1 to 0.2 millimeters. When perfect engagement, the nail is not cut properly on the contrary, the outrange of this tolerance, is cut out coarsely. Today, thanks to technological advances, South Korea has been able to narrow this chink to between 0.05 and 0.08 millimeters. South Korea, to achieve this goal, produces a special steel called "15CM" through POSCO which is specially made for this nail clipper. Many different advanced technologies are combined in this tiny nail clipper. Don't ...
