Pencil 2 tip

I have a suggestion:

When one draws on paper, the crayon always has a bit of resistance as it rubs the paper. (So to leave a bit of material as a mark).

The tip of Pencil 2 is way to hard and smooth and, on a glass surface, it very hard to have a non-wiggling gesture.

Having a slightly softer or textured tip would make it closer to the real thing.
