Best Fettling Knives: Trimming and Seam Cleanup Blades Ranked
As an Amazon Associate I earn from qualifying purchases.
A fettling knife does the unglamorous work that makes finished pottery look professional: slicing slabs, beveling edges, cleaning mold seams, and trimming away everything that should not be there. The classic design comes in two personalities. Stiff blades cut straight and true through firm clay, while flexible blades bend along curves to shave seams flush without gouging the surface. Handle comfort matters too, because fettling work tends to come in long batches. In this guide we compare the fettling knives that earn permanent spots on studio tables, explain when to reach for stiff versus flexible steel, and point out a few inexpensive extras worth adding to the same order.
