An adjustable spatula for forming a smoothly arcuate concave contour in a viscous material and a smoothly arcuate convex contour in the viscous material, independently of each other, with a certainty that the contour of the viscous material is consistent, and with using only one hand. The adjustable spatula includes a blade, a handle, and an apparatus. The handle extends from the blade and is gripped by a user. The apparatus bends the blade to form the blade into a smoothly arcuate convex contour to form the smoothly arcuate concave contour in the viscous material and bends the blade to form the blade into a smoothly arcuate concave contour to form the smoothly arcuate convex contour in the viscous material, independently of each other, without a need for the user to have to manually bend the blade, with the certainty that the contour of the viscous material is consistent, and with using only the one hand.
