Not sure how it was done back in the 1940s or thereabouts, when Case is believed to have introduced the rough black handle material. The way it's done now is that handle slabs are not molded or cut to "perfect fitment." They are molded slightly oversized, fitted to the frame, pinned, and then hafted to make the handles smoothly and perfectly fit the frame.
In the example you have described I can imagine two scenarios. Scenario 1 would be they used the same press tooling to create the mold dies for several if not all the different sized molds. This makes sense because that means they only had to make and pay for one set of press tooling, which they used to impress all the different mold die. Scenario 2 would be that they only had one mold, used it to mold large sheets of the material, and then sawed the various different size handle slabs from the large sheets.
In my experience the earlier rough black knives were a hard rubber material that looks like it was probably jigged like bone. That material had a flat looking finish. The later knives appear to be some kind of plastic, probably molded, that has a more glossy looking finish. Just my observations - I could be totally wrong.
