I'm went and bought some dip pens on a whim, having little experience in using them. I used to own an Ohto Rook and used a few Speedball nibs my professor had.

I only bought two, and I'm having the same problem with both. I'm used to drawing my contours in a 'pushing' manner (picrelated, making a line in that direction while keeping the same hand position), but it's causing the tines to flick and bend and splatter (I think I already broke a nib doing so, since it doesn't hold ink for too long). Is there like some kind of technique for this, or am I not supposed to be doing that?

Secondly, are these supposed to feel like they're scratching/stabbing the paper? I really don't like how it feels at all and feels a little unnatural.
