It's important to note that the goal is to set it up for drawing with the side of the lead, not the point. (he demonstrates the grip and drawing technique it's designed for toward the end).
I mostly prefer 2mm lead holders though because I'm too lazy to spend time sharpening and figuring out what to do with the shavings.
in some drafting, you can buy mechanical pencils which are basically graphite holders. They will hold a nice thick chunk of material. we used a small pallet of sandpaper to keep the tip sharp and learned to rotate the pencil while writing.
