| It might feel "overengineered" to people outside the Japanese society, but it actually just solves common issues here and it's not overengineering.
The rotating mechanism is the easiest to see this. First, Kanji signs are more detailed than the alphabet and uneven lines can make it really ugly/hard to read. Same issue with breaking lead, causes ugliness. Second, traditionally handwriting in Japan have been seen as a way to measure one's upbringing; you can fake looks and style but if your handwriting is bad, that signals that your parents didn't raise you well. This was(and still is in some places) the reason resumes have to be handwritten. So tools that helps your handwriting had uses beyond just utility. (my handwriting is garbage and I'm happy IT and tech jobs doesn't check this) |
I've used the Uni Kuru Toga for years and have converted a few people to it. I don't think it's necessary for everyone, but it's just a great pencil.
It's also worth investing in better than the cheapest lead you can find as well. I prefer lead that is a little softer, and writes darker, than your standard "#2" pencil lead. There are a few sites dedicated to reviewing pens and pencils that are useful, and some have added on side stores where you can buy sampler packs.
I also recommend Paper Mate Flair felt tip marker pens for ink writing, especially if you've ever struggled with keeping legible notes.
