Since last November, I've carried around this diminutive, stainless steel Kaweco Lilliput, along with either a Rhodia # 13, #14 & occasionally a #16 writing pad.
The Kaweco leather carrying sleeve makes sure that the cap will not unwind in the bottom of my small Fjällräven shoulder bag. There is just enough room inside this bag for writing supplies, a knife, a phone & a few personal items.
(For years I have lugged either a briefcase or backpack. Now a light shoulder bag is really all I need.)
The Stainless steel version of the Lilliput looks a bit more industrial than the rest of this pen series. I prefer its heavier weight over the aluminium versions. On the steel pens the cap threads seem to be cut sharper.
Even with a very small hand like mine, gripping the section while writing is quite constricting. But if I grip the Lilliput a little further up, by its cap threads (on the barrel), I get better balance & greater control of the pen.
Lilliputs are not designed for extended writing sessions. Perhaps a couple of A5 sheets of writing can be completed in relative comfort. I mostly use this pen for taking short notes, lists, & writing cheques. My ink of choice is Pelikan's 4001 blue/black cartridges (providing some water resistance).
This Lilliput is fitted with a 14c B stub (almost a CI) that I borrowed from one of my Kaweco Dia2 pens. A similar gold B nib-unit is now at Pendleton's workshop, to be made into "stubbier" & wetter writer (to match the dry Pelikan ink).
