This Is How Sewing Needles Are Made

Ever catch yourself binge watching “How It’s Made” videos at midnight? If not, this might get you hooked up for good!

Pins and needles are extracted from long coils of steel wire. The process lasts a couple of days, as these wires are snipped, straightened, sharpened, and cleaned. Finally, they are turned into the all useful needles. Similarly, pins and medical injections are manufactured.
