Tangi River Valley Bullshark Advanced Combat Knife

$3100 raised for the Navy SEAL Foundation!

The most advanced combat knife ever produced anywhere - and we auctioned it with 100-percent of the proceeds going to the Navy SEAL Foundation to honor the Navy SEALs lost 8/6/2011!


The Tangi River Valley Bullshark Advanced Combat Knife is the first knife made with a carbon nano tube infusion process, which will make it one-of-a-kind. Our best materials and our best work are going into this one - not because we make gear for legends.


But because we owe legends our lives and liberty. And nothing but the best will do. Yeah Baby!


This knife is a full scale, Special Operations Edition Bullshark Advanced Combat Knife, made from M390 cryogenically treated super-steel infused with nano-particles to create the ultimate super-strength blade. It is paired with a special DRED system self-draining handle and custom fitted concealex sheath with tek-lok clip.


This is the finest combat knife we've ever produced. It stands alone. There will never be another one like it. And to our knowledge, no one has ever attempted the nano-infusion we've done on this blade.We used our finest materials and hand-craftsmanship to build a blade worthy of the greatest warriors in the world.

The Tangi River Valley Bullshark Advanced Combat Knife - the first knife made with a carbon nano tube infusion process - and the blade made to honor the Navy SEALs lost 8/6/2011.

Mike at Re-New Sharpening in Rio Rancho, New Mexico, puts a fine cutting edge on the Tangi River Bullshark currently being auctioned to raise money for the Navy SEAL Foundation. Re-New Sharpening is one of three businesses who have donated their time to our charity knife project which was started to honor the servicemen and one military working dog who lost their lives in the Tangi River Valley, Afghanistan. Three more knives - one for the Army aviators, one for the Air Force special operators and one for the working dog, Bart are being built now - and will soon be ready for their own auctions.

Mike the Engraver at KaMo Engravers in Albuquerque did the diamond engraving for the Tangi River Bullshark Advanced Combat Knife which was auctioned to benefit the Navy SEAL Foundation. Mike is a U.S. Navy Veteran - and not only the best engraver in Albuquerque, but the only one we would have asked to do this very important job.


Contact Mike Holly at 505-883-4963 if you need an engraving job done that absolutely must be done right.

The nano-infusion and coating process is now complete.

The Tangi River Bullshark - with handle and sheath now completed. Next will be the nano-infusion process and the specialized coating which will complete the project.
The Tangi River Bullshark - now ready for handle and sheath construction - and the special nano-infusion process, which will make the steel as much as 100 times stronger than it is now.
The visible patterns in the blade are the channels which will hold the single-walled carbon nano-tubes. We have prepared for a long time to do this treatment to a special knife - and we are very proud that this is the one.
In ticronic wrap, the Bullshark is witdrawn from the forge and quenched. The temperature it is at the time of removal from the forge : 2100f
The bullshark after quench - an instantaneous drop from 2100f to 975f - begins the long, standing cool down to 125f.

This is a close-up pic of the raw engraved blade of the Bullshark knife we are creating to benefit the families of special operations troops. This will be a blade infused with single-walled carbon nano tubes - truly super steel .... and one of a kind.

Channels have now been hand-cut by diamond into the raw blade of a Bullshark Advanced Combat Knife, to facilitate the fusion of single walled carbon nano tubes into the surface of the metal. These channels will be beneath the surface of the black duracoat coating when the blade is finished - and barely visible. This is the only nano-infused blade we will ever make (the process is complex and extemely expensive) - and, although totally field-ready and built for immediate use by any troop, it will be a very special item when finished.

For those interested, our knives feature a zero-grind style at between 7.5 and 11 degrees. We do each of these completely by-hand and by-eyeball. There are no jigs at work here. Our grinder features a ten-inch wheel with a variable speed controller - and we run it at high pressures with a 70 duro contact wheel and 2 inch x 72-inch blaze ceramic belts. 

We do not, however, weigh our knives. If you are worried about how much they weigh, you must be preparing to take them into space. Hope you have a good trip.

Our steels have been LaTrobe Dura Tech 20CV, ELMAX, M390, CTS-204P, Z-FINIT Nitrogen Steel, CPM-20CV and a couple in N690 and Cowry X. We are always experimenting - and always looking for new materials and treatments. 

Our coatings are also specialized stuff: We use Black-T and Black Diamond DLC. Our blades are sent out to those two companies to accomplish that work, depending on the requirements of the project.

We do all our own firing and cryo work. Everything by-hand and by-heart.
