Yes that's right, the hole is where my hand is at. This is where he pushes the rolled tobacco through and cuts it with a knife. The horizontal part he stands on with his foot, creating leverage to keep the device upright, rather than having just a single pole that wobbles. The difference in style might be that the guy from your book, my guess, sells his tobacco commercially, whereas this guy on my photo only grows a few plants and sells it to locals in the village, or in neighbouring villages. Whereas Rajangan cutters are made in larger quantities on islands like Java and Lombok, this guy on Sumba made his himself, probably keeping in mind that volumes he grows each season.
