I have been searching for a scuttle for several months. I finally decided to have someone make a custom mega scuttle. This is the first pic he sent and says he still has some work till he lets it dry. I use a large shavemac brush and wanted something a good size.Here is his store https://www.etsy.com/people/andersenpottery
and here is the scuttle he is making for me.
