TWSBI Precision RT Pipe Pencil 0.7mm Black & 0.5mm Silver
I really wanted to like these pencils, but they aren't suited for me personally. They are very well made and attractive and exude quality just like all of TWSBIs' products do. The retractable lead pipe is solid and movement free when extended, and being retractable really enhances their usability as they can be carried in a shirt pocket without fear of injury. They are a great value with the extra leads and erasers included in the case. My issue is the undersize and slightly slippery grip section, which doesn't have real knurling like that of my favorite Pilot S10 mechanical pencils.
A fellow worker liked them so I let him have his pick, which was the black 0.7mm model. He loves it and uses it constantly, and thinks the S10 is too girthy, so I guess it's just a matter of feel and preference. I will still give it 5 stars even though it isn't my cup of tea.
