Sewing Needle:
A sewing needle or sewing machine needle is a long slender tool with a pointed tip. The first needles were made of bone or wood; modern ones are manufactured from high carbon steel wire, nickel- or gold plated for corrosion resistance. Sewing needle is used to produce a hole in the fabric for the sewing thread to pass through and to do so without forming any damage to the fabric.

Different Parts of a Sewing Needle:
The different parts of a needle and their functions are mentioned below:

1. Butt: It is the truncated conical shape at the top end of the needle which is needed to attach the needle with needle bar or clamp.

2. Shank: Shank is the upper part of the needle which locates within the needle bar. It may be cylindrical or flat at one side.

3. Shoulder: Shoulder is the section intermediate between the shank and the blade.

4. Blade: It is the longest portion of the needle from the shoulder to eye. This part is responsible for the most amount of friction between needle and fabric.

5. Long groove: There is a fine slot in the needle from its shoulder to eye. The needle thread remains at this slot when the needle penetrates the fabric and goes up and down.
