I've uploaded some images from one of my recent hole punching exercises, through a dual thickness of linen writing paper. As I've previously posted, I believe the ransom note holes were formed by a very similar, if not this very process. I have found, among over two dozen different objects tried, the concaved head of a 2" finishing nail to most accurately reproduce in shape and quality, the original ransom note holes. The nail is impacted by the hammer in an inverted position.
Kevin and I have had some recent e-mail conversations following his discovery of a Stanley nail set (not pictured here) in Hauptmann's tool inventory, so I've used a modern day version as a means of comparison.
What is very important to this type of hole forming process is underlying support of a suitable material, in this case a piece of softwood. This positions and stabilizes the process and also receives the cut out paper chads from the high impact punch process.
It's also interesting to note the difference in hole shape, a trait of the original ransom note holes, as seen in the holes created by the nail entering and exiting the linen writing paper. All of the holes were created with the same finishing nail or nail set.
This is a very basic punching process seen in many material forming industries, but utilizing the same common principle. I invite comments and questions about the evaluation.

My own experiments with over two dozen different objects evaluated, tell me clearly the holes themselves were formed with some kind of crude punching device, with a solid substrate beneath, mainly as determined by their inconsistent shape from one ransom note to another. The paper chads themselves, with a few exceptions, are quite cleanly removed, which again confirms the punch process used.
There are two main features of the ransom note holes: i) how they were physically punched and ii) how the holes were so accurately reproduced positionally, from note to note.
I've previously demonstrated a simple and effective means (first post in this thread) of reproducing the general shape and quality of the actual ransom note holes.
In terms of reproducing their placement from note to note, simplicity and effectiveness is key. Here's a very simple demonstration:

There is nothing more complicated required here than a simple template, eg. a piece of stiff cardboard with three established holes for use as a guide, which can then be lined up against the sheet of writing paper exactly the same way each and every time. Once the hole positions were marked, the writer could then punch the holes using the method previously described. It's relatively straightforward to see how easily the hole positions could be reproduced quickly and effectively, even if just a couple of folded sheets of writing paper were punched at a time.
