iron-shod

Of a horse, shod with iron horseshoes.

Of a wheel or other device, having a protective iron casing or strip.

And so it happened that before the elephant realized that his new enemy had leaped from his path Tarzan had driven his iron-shod spear from behind the massive shoulder straight into the fierce heart, and the colossal pachyderm had toppled to his death at the feet of the ape-man.
