The big thing now is the "multi-action" pens. . . Generally has; black ballpoint pen (medium point), red ballpoint pen (medium point), 0.5mm pencil and a fluorescent orange highlighter (or some other multiple of writing devices).
Fisher has them in 4 different styles/types.
There is a Yafa Quad-Action (3 exterior colors).
Staedtler has a nice selection. Their 3-way; Aura, Kombi, Trio, Mars Data-3 and Multi-3. Their 4-way; Multi-4 and Quadra.
ROTRING has 3 different set-ups (Trio Pencil - three lead sizes 3mm, 5mm, and 7mm, Quatro Data Lava Graphite - Black, Red, Blue ink pens, and 5mm pencil, Quattro-Pen Data - Stylus, Black ink, Orange Highlighter and .5mm Pencil). They also have 3 in a "600 series."
Waterford has a large line (all have red ballpoint, black ballpoint, 0.7mm pencil and stylus tips).
The only problem with them. . .if you do "allot" of writing with the pencil. They're not known to last "real" long.
I use a Staedtler Multi-4. Very nice !
