Potter’s Fettling knives come with two types of blades: a flexible single-edge blade that is 2.5 inches long and a double-edge blade that is 2 inches long.

These tools are essential for cutting clay slabs, removing mold marks from cast greenware, and leveling and smoothing uneven surfaces.

The single flexible edge is specifically designed for cutting delicate white clay bodies, while the double flexible edges are ideal for various cutting and smoothing tasks on stoneware clay bodies, allowing for work in both directions. Made from high-grade cutlery stainless steel, these knives feature oval handles that ensure excellent comfort and control.
