These don't look particularly serrated, but perhaps you need yet higher magnification. I would think that the stiffness plus thinness of the paper is enough for it to act like a knife, without needing serrations.
- nerdponx 10y agoThose all look pretty brutal to me, like a tiny piece of MDF.
- woliveirajr 10y agoPaper can blunt scissors due to mineral elements that are used [1]. I never searched for these paper magnifications pictures, but I expected to see small sand particles, or something like that. The fibers dominate, and already seem very dense, specially the folded paper picture.
