The Ultimate Guide to Knife Blade Steels: M390, MagnaCut, S35VN & More

When buying a premium knife, one of the first specifications you'll notice is the blade steel. While handle materials and blade design are important, the steel determines how your knife performs in everyday use.

A high-quality steel offers better edge retention, improved corrosion resistance, increased toughness, and easier maintenance. Understanding these differences helps you choose a knife that matches your lifestyle and intended use.

Whether you're looking for an everyday carry (EDC) knife, an outdoor companion, or a collector's piece, selecting the right blade steel is essential.
