Push knives. From all I can tell they are just smaller detail drawknives, not really designed for putting all your bodyweight on and hogging off lots of wood. Usually with neutral, in line handles, rather than swept back or off set to the blade. It or any drawknife can be used to push or pull cut. I do this often, when necessary with a full sized drawknife, though a dedicated smaller knife is more manauverable for push cuts. Is this what you are refering to?
