was an evolutionary improvement in its day. It is most effective in larger sizes.]]
This claw-shaped anchor was designed by Peter Bruce from [[Scotland]] in the 1970s.<ref>Bruce, Peter, {{US Patent|4,397,256}} 9 August 1983</ref> Bruce gained his early reputation from the production of large-scale commercial anchors for ships and fixed installations such as oil rigs.  It was later scaled down for small boats, and copies of this popular design abound. The Bruce and its copies, known generically as "claw type anchors", have been adopted on smaller boats (partly because they stow easily on a bow roller) but they are most effective in larger sizes. Claw anchors are quite popular on charter fleets as they have a high chance to set on the first try in many bottoms. They have the reputation of not breaking out with tide or wind changes, instead slowly turning in the bottom to align with the force.

Bruce anchors can have difficulty penetrating weedy bottoms and grass. They offer a fairly low holding-power-to-weight ratio and generally have to be oversized to compete with newer types.<ref>{{Cite web |date=2019-08-16 |title=The Best Anchor |url=https://refit.guide/anchor |access-date=2022-03-22 |website=Refit Guide |language=en |archive-date=20 November 2021 |archive-url=https://web.archive.org/web/20211120001853/https://refit.guide/anchor |url-status=dead }}</ref>
