This is a New Zealand favourite.
A lightweight four pronged grapnel constructed of steel and then galvanised.
An excellent rock anchor for fishing or in many cases on the end of nets and trawling for that main anchor you just dropped overboard! If the grapnel gets locked in rocks then one fluke will pull straight with heavy force and allow you to recover it from the rocks.
A real fisherman's friend.
Folding model available in 8mm galv or S/S simply folds flat.
Part numbers for models of anchors: 07111, 07112, 07113, 07114, 07115
