Seeing as you lot seem to have a reasonable breadth of knowledge for recommendations for a wide range of stuff today’s query is pens:

Our office appears to do a great line of cheap, crap, scratchy biro-a-likes.

I want a decent rollerball type thing that is nice enough to make sure I actually keep hold if it but not mega-bucks so it’s not instantly half inched off my desk (you can’t trust those civil and structural engineers).

Only looking at the £20-30 mark so still a Parker or something similar?

Ta.

Take a look at Cult Pens

I have a Kaweco Sport rollerball which is not too upsettingly expensive if it gets half-inched, but also distinctive enough that it can be retrieved from the half-incher.
For general writing I use a Graf von Faber-Castell Guilloche fountain pen which is outside your parameter envelope… and I still sometimes have to smack people who want to write with it!

Never accept expensive imitations.

Drac, I see your Uniball and raise you a G-Tec-C4

I’ve got a nice Lamy Safari one, doesn’t look much so has never been stolen, writes quite nicely, but I prefer a FP so don’t use it too much.

Too fine for me onewheel.

Parker Arrow Jotter is quite nice. (SAGA Version)
Lamy ABC Fountain Pen and a bottle of Quick.
UNI Kura Toga

I use a Lamy 2000 ballpoint for work.

Yes, it’s more than £30, but you’ll make sure you never lose it..!

Drac, I see your Uniball and raise you a G-Tec-C4

Nope. I’m with Drac on this one. I far prefer the feel of the uni-ball. It’s both more substantial in the hand, and slightly less fine on paper.

Oh God, here we go….

Pilot G2.

Foray Liquid Fine Pt are very nice.

Personally, for my own (non-stolen pens), I use G-Tec C4s

Uniball pens seem to run for ever and ever. The micro has a nice fine line as well.
