- rOtring Trio (from 2000's)
- Pilot 2+1 (2 ballpoints, 1 pencil) all steel with black etching
- rOtring 600 Trio (knurled section)
- Unbranded "rOtring Trio" clone.
All of these write quite well. Mechanisms lock refills solidly into place. The older rOtring 600 Trio is the heaviest, but the mechanism is so smooth. The Pilot 2+1 is my favorite, so well put together and was quite affordable when it was still in production.
