A palette knife is a blunt knife with a very flexible steel blade and no sharpened cutting edge. It is primarily used for mixing paint colors, paste, etc., or for marbling, decorative endpapers, etc. The "palette" in the name is a reference to an artist's palette which is used for mixing oil paints. Certain artistic techniques call for painting with a palette knife.
Art palette knives come primarily in two types:
- symmetric knife that ressembles a putty knife with a rounded tip;
- asymmetric knife where the working tip is lowered like a trowel from the handle and the tip is pointed.
