i found a reference to someone else suggesting extruding rollers to form the blade then heat treating it. which is another skill. heat treating these long thin blades without getting a warp would take real skill, even if you did do a finish grind. not much room for error at all. steel was variable, and temperatures were judged by eye, not electronics. no cnc machines in those days.
