His work is defined by the woodcut medium. He used sharp, angular lines and high contrast between black ink and white paper. This technique creates a sense of tension in every composition. In works like Grotesque, he used distorted forms to explore internal psychological states. His style combines the harshness of German Expressionism with a focus on narrative. He often carved directly into the wood block to maintain a raw and tactile quality in the final print.

Modern collectors value Steinhardt for his ability to convey atmosphere through minimalist means. His woodcuts fit well in contemporary interiors because of their bold graphic nature and monochrome palette. The work offers a direct connection to the early twentieth-century avant-garde. These prints provide a sense of history and manual craft. They remain visually striking without relying on colour to attract attention. His prints are ideal for those seeking art with a strong physical presence.
