His sculptures borrow widely from art-historical techniques and styles; such as carving and art-deco period's graceful smooth lines and streamlined forms, without the ornamentation. Kale's stylized forms are distinctly modern, but his practice uses some of the old techniques used by most sculptors: processes known to the Anatolian metalsmiths of the Early Bronze Age including hammering or repoussé work, sweating or soldering, filigree, and cloisonné inlay. Carnelian, jasper, nephrite, obsidian, and meerschaum were all used for ornament, and he uses obsidian.
