A modern pen today. Pilot Custom Heritage 91, FM nib. Indistinguishable from the Custom Heritage 92 as far as writing performance goes, or how it feels in the hand, but uses the large CON-70 converter instead of a built in piston filler. Hero Blue-Black ink, which I just felt like using for some reason, although it has a rather pungent smell, and isn't quite as nice a color as Pilot Blue-Black.
And a Parker twist action pencil, 2B 0.9 mm lead. The model probably counts as a 45. I claim no expertise, but for writing, I rather prefer older twist action pencils like this with either 1.18 or 0.9 mm leads.
Vintage fountain pen, vintage mechanical pencil, old decoy ballpoint (in case I feel like lending a pen to somebody).
Parker Vacumatic with Pilot Blue ink. Esterbrook 1.18 mm (or 0.46 inch) mechanical pencil. Cap actuated Parker Jotter which must be fairly old, since it was made in the USA, ST Dupont black refill.
A Black Waterman Laureat - I always struggle to remember that name, and a Parker 45 both with Diamine Sherwood that has been thinned 50/50 with water but remains a dark green ink,
