Saltwater fishing hooks should have a corrosion-resistant finish.

Bare metal won’t do.

The company VMC’s Coastal Black Hooks, introduced this past year, feature micro-thin layers of black finish for that.

The hooks -- available in a variety of models: inline, circle, offset circle, live bait and treble -- are engineered to be up to five times more corrosion resistant than traditional black finishes, the company says.

In fact, the hooks, meant for saltwater, last longer than any black-finished hook on the market, it says.

The hooks are engineered to be sharp and strong.

They're 20 percent stronger than tin hooks, according to the company.

Much more goes into making hooks these days than you might imagine.

You might know little about VMC, located in France, and its rich history.

The company was begun about 220 years ago in 1796 as a steel forge in France with another name: Viellard.

The family Viellard owned the forge, and hired a man with the last name Migeon to manage the business.

Migeon married a woman from the Viellards, and the company’s name was changed to Viellard Migeon and Company or VMC.

The company began making hooks in 1910.

VMC now makes 4 million hooks a day, manufacturing them 24 hours a day, distributing them around the world.

In the United States, the tackle company Rapala distributes the hooks.
