Fettling knife is for filing down strong materials like stone or metal. It is similar to a palate knife but stronger, longer, with a straight blade of metal attached to a handle and with rough surfaces on both sides of the metal. There are two types, one straight on both sides and the other rounded on one side. A fettling knife is used for trimming, smoothing and leveling out uneven surfaces on dry clay, bisque and fired glazes caused by beading or crawling.
