154CM is our top choice for our hard-use knives, and it's been battle tested and proven by the US military war fighters and international special operations forces in every theater of combat for over 30 years.
We've been using 154CM since the beginning.
It has earned its place in our lineup. Originally crafted for the aerospace industry, this steel can handle extreme stress, heat, and extreme lateral pressure. It's tough, wear resistant, and built for demanding situations. When the environment gets rough, 154CM stays strong. Corrosion resistant, and designed to keep an edge without chipping, this steel can take abuse and it just keeps going and going. With our proprietary heat treating process, this steel gives you the strength and reliance you need for a hard-use tool and extreme performance.

Emerson Knife handles are made from G-10, a glass filled epoxy laminate. Some models are available with different colors of G-10.
At Emerson Knives, we don’t add anything for flash. If it doesn’t serve the mission, it doesn’t go on the blade. The stonewash finish is a perfect example of that mindset—practical, durable, and effective. It's not there to impress anyone. It's there to survive, to perform, and to keep doing its job long after others tap out.
But the benefits aren’t just tactical. That finish is tough. It hides wear. It masks scratches. A satin blade might look great the day you buy it, but a few weeks on your belt and it starts to tell the story. A stonewashed Emerson doesn’t complain—it just gets better with time. It's easy to maintain, easy to clean, and it won’t show every fingerprint or smudge like a polished blade.
Ernest Emerson started making custom knives in his garage in 1979. He rapidly rose to prominence as a knife maker due in equal parts to his expertise as a craftsman, (tool and die maker), his artists eye for design, and his practical experience as one of the world’s most sought-after and respected hand-to-hand combat instructors.
Emerson’s work has been featured and exhibited at the Metropolitan Museum of Art and the Smithsonian Museum. There are only a handful of living artists who can make that claim. As an instructor in hand-to-hand combat and edged weapon skills, Mr. Emerson has taught the most elite warriors on earth, from the US Navy SEALs to the Guards of Parliament in London and everywhere in between.
He is the author of scores of articles, books, and videos regarding tactics, training and combat. As one of the most sought after instructors in the world he is in high demand for seminars and lectures to civilian, military and law enforcement agencies.
He is an inducted member of The Martial Arts Hall of Fame, along with such venerable names as Bruce Lee and Chuck Norris. In fact he is the only knife maker known who also owns and operates his own training facility, the world-class “Black Shamrock Combat Academy Gym” in Los Angeles, California.
At a time when knives are designed by graphic artists and 22-year-olds who never did more than use a knife to sharpen a pencil, the name Emerson and the company Emerson Knives stands head and shoulders above the rest.
