Pencil Lead Hardness (from Wikipedia)

Pencil lead is graded by hardness: a greater percentage of clay results in a harder lead. H (harder), F, HB and B (softer) are pencils of average hardness. Pencils ranging from 2B to 9B are softer still and are used for sketching; 2H to 9H are harder than average. A common American #2 pencil is equivalent to HB.

In order, the leads are (from hardest to softest) 9H | 8H | 7H | 6H | 5H | 4H | 3H | 2H | H | F | HB | B | 2B | 3B | 4B | 5B | 6B | 7B | 8B | 9B.

The harder the pencil the lighter the mark, e.g. Bs tend to a create darker colour that can be smeared easily.

These are good leads,...

These are good leads, but it comes out a bit too light for me. I find they last a long time, and almost never breakā€”it happened when I advanced the lead a couple clicks, but otherwise they're great for heavy-handed writing. I'm using these up first, then I'm going back to HBs. When I bought the black Kuru Toga, I wanted to try a variety, so here are my conclusions for use in writing numbers on spreadsheets at work:

B: Nice dark lines, but a bit on the bold side; the Kuru Toga engine seems a bit too slow to keep up with the wear so the lines look as if they could have been drawn with my old .5mm Papermate.

HB: Still nice and dark but finer. The engine still seems a bit slow to keep up with wear but it's not as pronounced as with the B leads. I suspect this is because I'm writing numbers and not the shorter strokes of Kanji. The spreadsheet is easily readable and copyable, and I can do things like write two lines of printing in the space normally occupied by one. (Whether the home office can read it without a magnifying glass is debatable. Heh heh.)

H: Lines are a little faint but readable and I have to boost the darkness on the copier at work for the reports I do, otherwise it comes out too light to read. The lines themselves are razor-sharp and seem to be in the sweet spot of the Kuru Toga's engine when writing numbers.
