I didn't know about this hero. Of course I immediately thought of Britain's legendary Steel Claw, though beyond having metal mitts the characters bear no resemblance to each other. It was funny though that the opening caption describes the Steel Fist "clawing." Art in the early episodes is by H. C. Kiefer, a capable middle-tier artist who worked in a wide variety of Golden Age genres. He was good in all of them, but he really shone in historical stories.
