Wood-case graphite pencils for technical drawing. Won't any old pencil do? Yes, absolutely. Though ideally, you want a pencil that's available in slightly harder grades than your regular HB - 2H is a good start; that sharpens easily; and which won't break up. If it looks good too, that's a bonus. Here then is the cream of the crop. All these pencils are the very best that we sell, from the planet's most respected pencil manufacturers.
