Slow Clay Centre's bespoke turning/trimming tool contains eight tools in one and is closely modelled on Jane Sawyer's Japanese teacher's tools. If you have ever attended Slow Clay wheel classes you would have been taught trimming/turning using this particular style of tool because one tool can do so much! 
 
Eight tools in one = a large and a small end (for large and small pots!) and each end has a flat blade, a curved corner, a right angle corner and a vertical blade.
 
See three videos on Slow Clay's website about how to care for them, how to use them and how to sharpen them to ensure a crazy good cut every time!
