The important thing about my pencils is not the brand, but rather how I sharpen them. I take a razor blade and remove the wood to expose 1-2 inches of lead. I sharpen the lead with sandpaper to create a long thin needle shape. This creates a tip that is much sharper and will last longer then a regular sharpened pencil.
The extra long point also changes how I hold the pencil. It forces me to hold it like a paint brush, which is at the end instead of by the tip. It gives me more movement as I can use my wrist and whole arm to create graceful and controlled lines.
At the end of the video I show close ups of the drawing in the background so you can see the different line work created by the long sharpened pencils.
