Question

why are tips of needle made pointed​

Answer 1

Answer:

The tip of a sewing needle is sharp because the area under the pointed end of the sharp needle is very small. Pressure exerted by a sharp needle is more on the cloth and can pierce easily through the cloth.

Answer 2

Answer:

1. The more the area the less the pressure and the less the area the more the pressure. This is why the tip of a sewing needle needs to be sharp.
2. This needle type is generally used for a sewing machine and for knit fabric sewing projects. Use a universal point needle if you are sewing with woven and knit fabric as it can slip through fabric waves. The needle is also not that sharp enough to destroy delicate knit fabrics.
