Abstract
A device for engaging and holding an article, such as a wood log, to facilitate moving the same, includes a bolt with a point that may be modified to a smaller than standard conical angle, the point having runout threads thereon, and a handle rigidly secured to the bolt at a location spaced axially from the point and projecting laterally from the bolt axis. A user can wield the device by the handle to strike the article with the point to cause the point to penetrate the article, following which the user can rotate the handle about the bolt axis to force the bolt thread into threaded engagement with the article. The device also has a shackle rigidly secured to the handle at a location in line with the bolt axis with the bolt and the shackle extending in opposite directions from the handle, so that the shackle can be grasped to move the article with the bolt in threaded engagement therewith.
