In recent years I've switched to drawing with mechanical pencils instead of wooden (traditional) pencils. Why? Mainly because of the extra detail I can achieve with the fine leads. Most of the mechanical pencils are Pentel, and I really like the Pentel GraphGear 1000, it's my favourite 0.3 'pencil', with 2B leads. I also use a HB 0.3 and a 4H 0.3, plus the same range in 0.5 leads. I keep a sandpaper block to fine point the end of the leads for the really close detail and then some more traditional pencils for light shading and covering larger areas.
Do you have any favourites when it comes to drawing with pencil? What have you discovered that works for you? Or what hasn't?
