Spirally wound paper products are disclosed having desirable roll firmness characteristics and softness properties. The rolled products can be made from a single ply tissue web formed according to various processes. Once formed, the tissue web is subjected to a shear-calendering device that increases the fuzz-on-edge properties of the web and preserves the bulk of the web when wound.
