Cool. I wonder if this was useful in forestry because the punch cards were quite sturdy, compared maybe to a clipboard full of forms, or field notebook. A little more detail from the cited article: "The personnel of each crew includes a forester, a crew chief and a tallyman" Later: "All records are in code: Mastery of the code is a large part of the preliminary training..."

I wondered what they used to guarantee the holes would be rectangular and correctly placed. From the picture, it seems the holes were partly pre-cut. I fear that increases the risk holes could accidentally appear when folding, spindling or mutilating such a card. That would make them less sturdy than ‘normal’ punch cards. On the other hand, given that this survived reading in a punchcard reader even once, those not-punched holes must have been fairly sturdy.

  I can't seem to find a picture online, but a blind person once showed me a "pocket brailer" that was a sort of sliding stencil that could emboss crude braille on thick stock with a special stylus. It was his equivalent of a notepad. Maybe stencils were made for the Port-A-Punch to suit different jobs.

    You mean https://www.amazon.com/Lines-Cells-Braille-Writing-Stylus/dp/B016CQVULS https://www.amazon.com/Lines-Cells-Braille-Writing-Stylus/dp... or https://en.m.wikipedia.org/wiki/Braille#/media/File%3ALucy_Sergent%2C_26%2C_who_has_been_blind_since_birth%2C_writing._She_attended_the_Kentucky_State_School_for_the_Blind_for..._-_NARA_-_541365.jpg https://en.m.wikipedia.org/wiki/Braille#/media/File%3ALucy_S.... They are used with regular Braille paper. Apart from being thicker and sturdier than ‘normal’ writing paper, there’s nothing special about that paper. The Braille writing tool basically forces you to punch Braille dots in the paper at the correct positions/distances (interestingly, as you punch the dots from the backside of the paper, you have to write a mirror image of the text) The photo in https://commons.m.wikimedia.org/wiki/File:IBM_Port-A-Punch.jpg https://commons.m.wikimedia.org/wiki/File:IBM_Port-A-Punch.j... doesn’t show anything like that in the tool. Also, zooming in, I think I see that this doesn’t use standard punch cards, but ones prepared to make it easier to punch out the holes. You can’t see it in the photo, but I would guess that the bottom of the device has holes through which the chaff falls out, possibly with a collection box, just as that of a hole punch. So, you push a punch, probably slightly smaller than the hole to make, on the center of the hole to make, onto the paper, shearing of the paper along pre-weakened lines.

      re the brailers: Those are close, but the one I was shown was smaller; truly pocket sized. This was ~20 years ago. I doubt they are really sold anymore, because a small handheld tape recorder is easier for "notes" if you are blind.

        https://en.wikipedia.org/wiki/Slate_and_stylus https://en.wikipedia.org/wiki/Slate_and_stylus shows a business card sized version. And I don’t know how large the market is, but https://www.maxiaids.com/braille-writing-slates https://www.maxiaids.com/braille-writing-slates has both small and large ones for sale. I would guess they still are used a lot because, in large parts of the world, the blind, if not the population, can’t afford to own a small handheld tape recorder (think of Nepal and poor parts of India) They also have the advantage over tape recorders that those around you cannot hear what you record.

  Presumably if the data were to be archived or processed multiple times it could simply be duplicated onto regular punch cards.
