When the surface area of a material is quite large, it can exert lesser amount of pressure on another surface; while the object with minimum surface area can put in the highest pressure.
Hence, the tip of the needle should be very sharp, so that it has the minimum amount of surface area and can exert the highest pressure on the surface to which it is applied for sewing.

HEY!!
✔In a sewing needle tip, as we know, the surface area is less. Hence the pressure exerted will be more. Greater the surface area, lesser the pressure and lesser the surface area, greater the pressure. So, as the surface area is very little, the pressure exerted will be more.
