A needle point is a very narrow, sharply tapered profile that comes to an extremely fine tip. It penetrates with minimal force and is the most fragile point geometry in common use.
The taper is long and thin in both dimensions, so the cross-section at the tip is tiny. That is what makes it enter material so easily. It is the profile used on stilettos and on some slim gentleman’s folders where a delicate look is part of the appeal.
It usually carries very little belly, so slicing is not its strength either.
A needle point will break if you lever it, twist it in a cut, or drop the knife point-down onto a hard floor. That is not a defect; it is the direct consequence of the geometry that makes it pierce so well.
If you want fine-point capability with more durability, a clip point gets you most of the way there with meaningfully more steel behind the tip.
