A surface friction reducing and hydro-tension releasing knife blade having a cutting edge, a back edge, a first side, an opposing second side and a tip. A plurality of spacedly arrayed protrusions on the first side and on the opposing second side between the cutting edge and back edge provide a plurality of spacedly arrayed inclined ramps from the planar blade side to a crest that separate the item cut from the blade side to reduce surface friction and to relieve hydro-tension.
