IF I recall, they made a "home-made" rasp of sorts. A wood body/handle. It would hold a bunch of little steel blades, set close together. In fact, to insert that last blade, one had to drive it in. The blades were cut from old saw blade steel, and file perfectly flat and square at the edge. Mainly a two handed "weapon" to remove a lot of wood, very quickly. I just can't remember the name they called it. There was also a small steel rasp in that tool kit. It was a "store-bought' item. Any clues out there?
