How It's Made - Nail Clippers


The nail clipper was invented in 1896 in the United States, and soon it was at everyone's finger tips. by 1902, it was sold by dozens for  $2 in US currency as an alternative of scissors. it was an idea that just clip.


More then a century after its invention, the nail clipper is still behind many well groom hand. Its popularity number in a million and no manicure set would be complete without one. 


The production begins with this elaborate die. It is about medium in length, it has 12 differnt shape openning. hydraulic machine repeatedly forces steel sheet through various opennings as the sheet moves forwards. With each stroke, the part looked more like nail clipper jaws. The clipping area starts out straight and blunt and gradually become concave. The machinery also cuts and shapes the hole for assembling the nail clipper. In just one minite, a total of 80 strokes generate a dozen nail clipper jaws.


Then the clipper jaws vibrates a brace of stones and organic acid for up to 20 hours. This gentle polishing makes the part glim but doesn't ruin the edge. At the next station, a worker aline a pair of jaws for assembly. Using a machenical press, he drives rivets into the hole at the graping end of the jaw. he flips the assembly jaws and insert the other half of the rivet and then press the tube tightly together. 


The rivet loss the graping end of the nail clipper together so the two jaws can't be twisted apart. Next a worker smooth the edge of the clipper of the graping end against the brace wheel. This griding evens any irregulairty and makes the two clipper jaws as one at the graping end.


Attention now turn to the clipping end of the clipper, after locking them in the device, a worker grind the concave edge until they match up. These nail clipper jaws are now ready for the lever. But the lever itself still needs some work. 


Lever then fed one at the time, and cafet little hole, the hole is just 1.3 millmeter in deameter. A worker now install a bow in the clipping end of the jaw, this bow has little hole at the end of it. keep press the jaws together and now it is time to attach the lever. he insert the pin in the hole of the lever and the bow he pinch the pin with a piler to secure it. Now it is moving freely on the cutting jaw. All the pieces of nail clipper have come together but the assembly process has left oil on this tool. It is time to clean in a special tub. Sound wave keeps the water moving and distribute the soak and keep them clean. 


Once they dried a worker uses a combination of acid and positive electro to edge the company and item No. onto the nail clipper, the next employee sharpen them  it takes skill and practice to get them just right. He holds the nail clipper to a light and check the alignment of jaws as he opens and closes them. 


This cardboard test confirms these nail clippers are up for the job.
