Method of making razor blades

While I was looking for something unrelated, I stumbled over this patent from 1914;
For the mechanically inclined among us - well, the subset of the mechanically inclined that has access to a well supplied workshop at least - it looks like one could put one together in the shed and start cranking out DE-blades for fun and profit... it grinds, wraps, punches, folds, and packs blades - ready for shipment and sale.
