What is a hb 2 pencil?

I've never heard of an 'HB #2' pencil. I'm saying that no one makes them! But this is what I know about pencils. 'H' pencils are typically used for graphic drawings. The lead is harder and the lines tend to be lighter and thinner. The lead is less prone to smearing. The higher the number, the lighter and harder the lead. Then we have the 'B' pencils. The lead is softer, darker, the lines tend to be thicker. As the number gets higher, these qualities increase. A 6B pencil gives a very dark, thick line. These pencils are used more commonly for sketching in the typical 'drawing', like an artist's picture. These leads smear on paper easily! As an architectural student, I'm required to use an 'HB' pencil. This is just a blend of H and B leads. It still has an annoying habit of smearing on vellum! I usually stick to H2 pencils and higher whenever possible to keep my work clean!
