Generation Changes to the Pentel S5x Series Pencil

General Mechanical Pencil Discussion

Here is the last article I am writing for inclusion in the next version of the Pentel Pencil Identification Book. Along with the “Possible Release Order of Early Pentel Stick Pencils” and “Types and Generations of the Pentel Eleven”, this new article “Generational Changes to the S5x Series” will be included.

Generational Changes to the S55.pdf (1.0 MB)

Please let me know if you see any issues, typos or have more information.

I am going to try to have the next version of the book out before Christmas, when I am off work.

Here is a gen 1 S55 with a gold top with a frosted body. I can send a better picture later if you want one.

I also some that may be gen 2 but have the sharper grip like the gen 1 S5x pencils. These have the 4mm tip thread. In fact, without removing the tip it is not at all easy to tell gen 1 from gen 2 pencils.

We know that Pentel never threw anything away so there is likely some blurring of the generations.

Yes, it surprised me that my Gen 2 pencils did not have the sharper grip.
