Thanks for sharing the link to ITOYA 
Just to clarify, the original post in this thread is for a pencil made by ‘ITO’, the defunct stationery and office equipment maker, not ITOYA, the upmarket stationery store in Ginza. Although ITOYA produces its own lines of pens and pencils, they are clearly marked ‘ITOYA’ and not ‘ITO’.
Interestingly, ‘ITO’ is called by its initials ‘I–T–O’ in Japanese, i.e. ‘eye-tee-oh’ instead of ‘ee-toe’.
No problem.
I am the one who is grateful for making the corrections.
This is all very interesting, and when I started to do some research, I came across new and unusual situations that made me wonder if it was just the same brand, or if they were different companies with similar names.
And as far as I knew, ITO-YA was always written in capital letters and separated by a hyphen. However, there were situations in which it was written simply as ITO.
But there is one detail that I only remembered to mention later, and that made me certain of my statements, is that I knew ITO-YA (written this way) because its line of pencils is quite popular in certain countries, such as India, for example. And the Indian version of Amazon (Amazon.in) has a line of these pencils, which follow this writing pattern.
Pencil in the OP looks like a chopped LION 3250 with a custom grip. I kinda dig it.
Looks like if you combined a PS1045 with a LION 3250
It does seem that ITO was a separate company to ITO-YA, and was responsible for the pencil in the original post. I have a set of ITO technical pens with the same logo as seen on the pencil clip, which the box attributes to ITO & Co, Ltd.
Whether ITO was the actual maker is unclear, as I have another pen set with the very same pens, but this time by Sakura:
If Sakura was the manufacturer, is it possible that they also made pencils for ITO? I also noticed that the tail end of the ITO pencil is very similar indeed to these Gakken pencils (fourth and fifth from left in the top photo), but with a fixed clip.
It does not surprise me that ITO was also an office furniture supplier. This seems to have been a common fate for drawing instrument manufacturers, such as Riefler in Germany and British Thornton, both reinventing themselves as office furniture businesses after CAD killed off the technical drawing market (British Thornton finally went out of business in 2020).
I have two of these and were blown away by how nice they were. 2 for $20. Had never seen them before, definitely won that gamble.
