Cut leather-hard clay, wax, and other materials easily with DiamondCore Tools’ Pottery Knife.

With its coated, stainless-steel blade and attractive hardwood handle, this simple yet essential ceramics accessory is one you’ll reach for again and again. An adjustable thumb screw allows you to open and secure this straight blade, similar to a fettling knife. Just loosen the screw, extend the blade, then tighten the screw again. 

Laser-engraving personalization makes our Pottery Knife a great gift for the ceramic artist in your life or a practical treat for yourself.
