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.



6. Short groove: Short groove is the slot on the side of the needle towards the hook or looper. It assists in forming the loop of needle thread.

7. Eye: Needle eye is a hole at the tip of the needle through which the sewing thread passes. It prevents the sewing thread form damage during sewing.

8. Scarf: Scarf or clearance cut is the portion across the whole faces of the needle just above the eye. Its purpose is to enable a closer setting of the hook or looper to the needle.

9. Point: It provides the best penetration of material according to its nature and the appearance that has to be produced.

10. Tip: Tip is the keen extreme end of the point.
