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.

I love this knife! My Emerson PUK exudes the highest quality and the craftsmanship is superlative. No surprise there - it's an Emerson. The PUK design is extremely functional and aesthetically pleasing. A wonderfully balanced knife, it feels great in the hand and offers a sharp and sturdy blade edge. The fixed blade aspect is a great alternative to equally outstanding folder designs, and my PUK fits/snaps perfectly into the provided sheath. My only wish, is that it should automatically come with a belt clip for the sheath, rather than having to purchase separately, and incurring the high shipping cost for just one clip.
This knife is the perfect for size for EDC. Thuderstorm finish is most excellent and the ergonomics as always is on point. The custom laser engraving is a very welcomed feature.
This is the second PUK I have bought. Almost everyone on my security team carries this one on their vest and the EP guys have it integrated into the suits.
High praise.
I've owned and heavily used this knife since 2010. I carried it in both active military service and on civilian duty. It fits perfectly in an M4 magazine pouch or even inside a front pants pocket. I've used it to baton wood for fires many, many times. I've beaten the **** out of it. I've had it sit in a go back for years as well. Through 13 years of off and on heavy use, the only thing that ever happened was the handle scales needed to be re-tightened. The blade coating took a long time to take the worthy wear it now has. The sheath is excellent and still clicks in as good as the day I bought it. The blade re-sharpens to a razors edge with ease and the thing had never rusted despite many trips through the woods in winter and periods of neglect. It is easy to carry and invincible. It is at home in the woods or on duty.
I bought this knife along with the Government Mule. And I'm going to be returning this knife, but still giving it a 5-star review...Why? Read on!
First, the reason for my return...I have larger hands, and unfortunately this knife's handle is JUST a little too short for me to get a secure grip. Since I was going to be relying on this knife heavily, I didn't want to risk it. So I had to box it up within minutes of getting it. I'm heartbroken over it because this knife is absolutely perfect.
The design and shape of the blade are probably my favorite out of my entire collection. There's just something about it that is beautifully functional to me. Fit and finish are superb. The knife is just wonderful in every way. It is light, sturdy, compact and concealable. This would make a superb EDC knife, and supplement any go-pack/get home pack or anything like it in a big way.
The handle is slim, comfortable, and textured JUST enough to give you some great grip but won't chew up your hand over long sessions. The sheath is superb, fits tight and allows you to carry it in any orientation without fear of losing it.
That's about it folks. If you're looking for a fantastic all-around knife, you will be well served with this beauty. I'm crushed that I can't keep it, but I'm thrilled that its bigger brother fits the bill flawlessly for my hands and needs.
Is there a window punch on this?
Fantastic fixed blade. I use the sheath to lock it on my belt upside down and never worry about it slipping out. Also can convert to a boot knife - just 2 Phillips screws to remove from the sheath and drop in boot.
One if the best feeling fixed blade knives I've ever owned..
