Can a notebook pen clip scratch or mark a soft cover?
Risk depends on contact area, spring force, edge geometry, trapped grit, cover material, and movement.
Research boundary: Existing products already solve much of this category. This page documents tradeoffs and an unverified narrow hypothesis.
What to check
- Narrow contact points concentrate pressure.
- Hard edges can rub during pen removal.
- Dust between clip and cover can act as an abrasive.
- A soft pad reduces hard pressure but does not guarantee zero marks.
