Note: Ansom used the pliers. Just not to their full potential. He was able to slay uncroaked in a single hit with them. Wanda, being attuned, can also Decrypt with them.

The real question is... Is Stanley using the Hammer to its full potential? Could anyone with the hammer tame dragons? Or are the abilities Stanley uses representative of the Hammer's power for the Attuned?

Note: Ansom knew he wasn't attuned. Ansom stated Stanley was. Perhaps Attunement is something that is visible to the characters.
