In 2022 I filed an application for a patent for the Black Box concept knife. The idea of a fixed blade with part of the blade retracted in the handle is a concept I designed back in the late 90's which was put in production by Masters Of Defense called the Phoenix. That knife had a button lock mechanism. For this Black Box concept I took the idea of the Phoenix and completely re-designed the entire knife, from the shape, to the locking mechanism and the sheath. Then I found a manufacturer (Ketuo in China) who was able to produce these for me at the quality level that I wanted and an affordable price.

The concept allows the user to carry a 4" fixed blade with part of the blade retracted in the handle and only 1.5" exposed. The sheath holds onto the tip of the blade and as the knife is pulled out, it extends the blade. The patent pending mechanism locks the blade open. When the lock is disengaged the blade slides back in the handle and the knife can be put back in the sheath (it needs to be done in this order for a safer and trouble free re-holstering). The sheath features a clip which allows the user to secure it to garments and gear. The system allows the user to carry a 4" fixed blade in a compact package. The Ek version is the non ring version of the Black Box; this concept lends itself beautifully to the Ek design. If you are not familiar with the Ek brand, this knife company started by John Ek in 1942 produced combat knives for our servicemen and these knives have been present in many armed conflict since WWII. 

4 different blade configuration are available: Dagger (no serration, partial serrations or full serrations) and single edge.

About the Maker

"I was born in Texas where I have lived most of my life, but I also lived in Indonesia, Taiwan, Singapore and Thailand. I have been interested in knives ever since I was very young. I have been practicing different martial arts over the past 30 years like Okinawan Te, Thai Boxing, Northern Shaolin and Kali. These trainings, along with my experiences as a Recon Marine, gave me the perfect background to design both defense and utility knives. During the time I spent at 4th Recon C Company, I was a Team Leader in charge of a Deep Recon Platoon. I am trained in Artillery Call for Fire, Naval Call for Fire, SOTG, Amphibious Recon and many in-company trainings. I have a Bachelor Degree in Criminal Justice and an Associate Degree in Fine Arts. I started making knives part time while I was in College and decided to become a full-time knifemaker after graduating. I have been making knives since 1988, constantly researching, refining and developing this craft. I am a member of the American Knifemakers Guild since 1994. At that time I was the youngest Guild Member. My work has been awarded several prizes: “Best Utility knife” at the 1992 Lone Star Knife Show in Dallas “Beretta award” at the 1995 Guild Show Fighting Knife Magazine’s “Knifemaker of the Year” award in 1996 “Best High-tech Knife” award at the 2001 SICAC in Paris, France.

I began making knives in 1992 and have been fortunate enough to have worked with and learned from some of the best knife makers in the world. The maker most responsible for my progression is Stan Fujisaka of Kaneohe, Hawaii. I had been making knives for several years before I met Stan, but he opened the door to a new level of knife making for me and shared his considerable knowledge with me freely. I will continue to refine my craft and to build on all that I have learned so far. I enlisted in the United States Marine Corps in 1997 and spent over 10 years in its service. I served as a heavy equipment mechanic, an Embassy Guard in foreign lands and a Senior Explosive Ordnance Disposal Technician in many of the world's garden spots. I have trained in Explosive Dynamic Entry, Advanced Access and Disablement, Improvised Explosives and Devices, Weapons of Mass Destruction, Close Quarters Combat and many other technical and tactical skills. I have deployed to, lived and worked in Laos, Thailand, North and South Korea, Peru, Mozambique, South Africa, Iraq and many other places in between. Since my departure from the Marines I have worked as an Unexploded Ordnance Technician clearing unexploded munitions, from projectiles to land mines from old training areas. As an EOD Team leader in Iraq, I oversaw over 300 EOD responses and over 100 Improvised Explosive Devices where rendered safe. All of these experiences have given me a unique view of how I think knives and tools should be designed, made and used. I look forward to many new things during this new phase in my career. There is a lot of work left for me to do to get ready for more work to come.

John Ek wanted to contribute to the American war effort during World War II. From his shop in Hamden, Connecticut, Ek built custom knives specifically for soldiers, sailors, airmen, and Marines. He even built a knife for the Commander-in-Chief, American President Franklin Roosevelt. Mr. Ek, who also employed disabled Americans, produced six models of knives beginning in 1941. He referred to these knives as “Ek Commando Knives” as they were purpose built for close quarter use that would become a hallmark of the US Marine Raiders, US Army Rangers, First Special Service Force, and Office of Strategic Services’ Operational Groups. To purchase an Ek Commando Knife one had to send in proof of military service. The knives were numbered and a log was kept to tie the number to the owner. Americans have carried Ek Commando Knives in World War II, Korea, Vietnam, Afghanistan, Iraq, and countless other locations in between. John Ek’s knives live on today through Ek Commando Knife as a testament to his ideas, skills, and unflinching patriotism.
