It is a sewing needle.
A pin is used for temporarily keeping pieces of fabric in place while hand sewing, or sewing on the machine. After sewing you would remove the pin. An actual pin is a very thin piece of metal with a tiny head at one end. This head is to stop the pin slipping all the way through the fabric.
''Pin cushions hold pins for sewing. They also sharpen the pins with the material that's in the center of it.'' -Quoted by my 7th grade sewing teacher.
It depends on what kind of pin. Some examples are: pin (for sewing) = sikah (סיכה) pins (for sewing) = sikot pin (for bowling) = peen (פין) pins (for bowling) = peenim (×¤×™× ×™×)
