Is this better than a fixed pull-through sharpener?

Yes for flexibility, because the angle dial can follow a blade's existing bevel. Edge quality is still below a whetstone or a guided rod system.

Will it damage my good knives?

The carbide stage removes metal quickly, so use it sparingly on quality blades. For expensive knives, a stone or guided sharpener is gentler.

It handles scissors, which is a common use. Serrated edges are best touched up only on the ceramic stage, if at all.

No. It is a dry pull-through tool; wipe it clean after use and it is ready again.

Yes. There is no clamping or angle holding to learn, and the dial takes care of the angle.

Use it for quick touch-ups when a knife drags, not every time you cook. Frequent carbide use wears blades down faster.
