Love Pentel Graphear 1000, have multiple distributed throughout the house/workshop and backpacks :)
The other I really like is UNI Kuru Toga, the plastic one (shrug). The twist mechanism actually works; it is slightly wider thus more comfortable (for me) for longer writing sessions.
The twist mechanism really does work, but unfortunately it is easy to damage (for me). I damaged two kuru togas in the span of 6 months, very frustrating. The twist still works, but it is very wonky.
In my case - as my basic Kuru Toga died last week, the plastic of the casing just under the mechanism / just at the end of the body next to the rim broke down - because of the pressure i'm assuming, still a great pencil. I'm buying the advance one next.
