Description:
The movable jaw is a sliding quick-adjust using rack teeth. The handle includes an oil reservoir with a screw-on cap. The end of the cap has a screwdriver blade. The curved folding "blade" that keeps the oil reservoir cap from unscrewing can be used as a tack-puller, packing-remover and horse hoof cleaner. The straight folding blade has a sharp tip that can be used as an awl, punch, or scraper.
