The teeth in the Lawn Jaws weed puller are about four times deeper than those on needlenose pliars and are designed to grasp the root of the weed. The slotted jaws allow mud and debris to escape the jaws, reducing clogging from soil build up. This makes for a consistent approach to weed pulling, The Lawn Jaws are built with a soft, slip-resistant grip and rust resistant, stainless steel with a chrome finish.
