Just tried to sharpen a builder's pencil and the two wood halves came

Pencil sharpener for normal pencils is blunt.

I am now considering a propelling pencil with a thick lead for use in
marking up work.

Anyone else doing this?

If so, which lead thickness?

Cant advise on thickness but if you do want a thick one, how does
5.6mm
sound?

Yes, I did some research before asking the question.

I would just buy one and try it. Gotta be a reason why carpenters pencils
are so big.

I thought that they were just normal thickness, but wider to stop them
rolling away.

The ones I've seen have an oval cross section and a rectangular lead,
presumably so they can make a nice thin line without wearing down too
quickly.
