Palette knives are also used in cooking, where their flexibility allows them to easily slide underneath pastries or other items.
Art knives come primarily in two types:
palette knife resembling a putty knife with a rounded tip, suited for mixing paints on the palette;
painting knife with a pointed tip, lowered or "cranked" like a trowel, suited for painting on canvas.
While palette knives are manufactured without sharpened cutting edges, with prolonged use they may become "sharpened" by the action of abrasive pigments such as earth colors.
