That wouldn't surprise me if this is the quickest video in the entire series, but this is a triangle turning tool. I get asked about this a lot and they seem to be surprisingly difficult to find given how useful they are, but this is called a triangle turning tool. I've got it from Patrick Crafts in the UK. That's probably the term you want to search for to find it somewhere else, but it's just basically a triangle cutter on the end of a handle and it's fantastic for a moving clay at the base of pieces because it pulls it away rather than the wooden knives that don't really separate it out. This slices it. So as long as you don't cut so much clay off that it loops back and gets back on the piece, it's really good at scooping the clay away from the work and gives you a really crisp undercut to the base. If you're using the hardly a noble bats, it's not recommended to use metal tools. I do just don't push down into them too much, especially not with the tip of it because you can cut. But as a general rule, as long as you're not pushing too hard, you'll be fine. But yeah, triangle turning tool. I highly recommend these. There only, I think this was six quick from Patrick Crafts. I'll put a link to that and then if you want to find one internationally, set your triangle turning tool or find something that looks like this.
