We show that Neptune-scattered planetesimals of a few Earth masses could have excited the eccentricities of the vast majority of bodies in the primordial Edgeworth-Kuiper belt. This could result in sculpting the belt to its currently observed structure and in depleting most of its primordial mass by: (i) injecting most of the bodies from the stable into the unstable regions in the inner belt; (ii) enhancing the role of mutual catastrophic collisions in the outer belt.
