The Double Push, rOtring 400 and Esprit and all in the middle of the graphic above - to give you an idea when they were sold.
Basically, the Metal Double push and the 400 are almost the same pencil (one says 400) and has a few minor changes. The Esprit came later. Again – almost the same/similar pencil but the Esprit came in a lot of sizes and colors.
The Tikky video has chapters so you can jump right to the pencils.
@metal_punching_gripyou are correct!
And I can’t believe I overlooked these when I was looking for other push button double knocks in my collection. I had them stored away, still in the box which is unlike me, and TBH I had forgotten about them.
The internals and grips (at the least) are interchangeable. I have to be at work early today and didn’t have much time, but I’ll put together a short video this weekend.
But hey! You may be solving the mystery of who really made these. In my research I saw a few posts where some people said they believe the manufactum was made in Japan.
I own one of these. They’re a very good EDC pencil- I think they’re best compared to something like the Blick Premier or a Graphgear 1000, but beat out both in terms of writing experience and construction/design. Their limited availability is absolutely a pain though- wish a US retailer would pick them up.
From my knowledge I don’t believe Luddite makes its own mechanisms so both are likely manufactured by one of the major Japanese companies— I don’t recall the name of the “parent” manufacturer.
Thank you @metal_punching_grip for the nudge to go look in my closet.
I had completely forgotten i had bought these. Maybe a sign of too many pencils lol?
