The Paisley Scraper proves itself indispensable for sculpting, shaping, and refining leather-hard clay. The tight inside radius of this tool is good for working around joints (such as the inside of a teapot spout.) The Paisley Scraper Rib is available in
Extra-Fine edge (24 teeth per inch)

I like to use this rib to lay down parallel incised lines for inlay, but can also be used to remove and shape clay prior to smoothing and polishing up with a Polymer Rib. 

Made from a flexible cutlery-grade stainless steel.
