there are other videos on the mottura on you tube, sochilons, and some others, but I saw one by annie, possibly annie1 or some number. it shows the tool very well. I had the link written down, but the ink got runny after I spilled something on it, I think the paper was trashed. I think it was posted 3 or 4 years ago.
go to youtube and search for mottura. look for annie in the results.
Wake up and smell the Kafka!!!
