For	Bock nib option Piston filler Lighter than the metal-bodied models	Piston filler at a cartridge-pen price Reported to hold ink for weeks without hard starts Standard #6 nib unit takes JoWo Comfortable resin body, light in hand	Solid brass gives it real presence and it patinas Piston filling Retro proportions
Against	Less distinctive than the V-series Thin review coverage	Trim and finish are plain next to the V-series Piston is not user-serviceable without the Asvine tool	Heavy — a wrist-tiring pen for long writing Brass tarnishes if you'd rather it didn't
