This is another anchor mainly used on boat. You could also call Claw or Bruce anchor a single fluke anchor. But below is description from US Patent.This is an anchor in which an L-shaped shank has a single fluke pivotally secured to the shorter leg of the L. The L-shaped shank lies substantially in a plane. The fluke pivots through the plane but not in the plane. The fluke has a single triangular, planar fluke member which may be disposed in the plane. The longer leg of the shank is arcuate and the anchor cable is attached thereto. Some anchors are seldom used nowadays but we still list them for your reference.
