Comments about Pilot® Razor Point Pen, Extra Fine Point, Red, Dozen:
The extra-fine tip is supported by a metal sleeve, but it is still not rugged enough for routine use. The tip has a tendency to slide into the sleeve, leaving so little felt exposed that the metal sleeve starts to scratch on the paper. This failure mode happens well before the pen runs out of ink and before the tip wears normally. Over half of mine failed in this fashion.

switched from technical pens (i.e.rapidograph) to these pens for notes and preliminary drawings of concepts. this porous point pen delivers ink to paper with the lightest touch. consistently fine line, with minimal halo on almost all paper types. have tried many, many types and brands in almost 20 years. have found nothing nearly as good for my use. long lasting ink too.

We use it at an architecture firm to review documents and add notes. It has a very fine tip so small print can still be read easily. It does not bleed through. When the pen gets old, the tip gets worn down and it should be tossed.
