well, nobody wants a soft leadin my line of work, I'm very up to date on lead and their varying hardness levels. When I first started in drafting, we used to manually draft all of our design documents, plans, sections, and isometric drawings, all with a straight edge, and a lead holder. Not a pencil, but a mechanical lead holder, oh and the compass.
needed several to hold the different leads, for different objects on the face of the drawings. Some objects needed thicker darker lines, some finer and sharper, hence the requirement for leads with different hardness.
Chris, you sour and WV just keep your thoughts to yourselves on lead holders with hard lead in them.
