What is a Prortype...?
Our New catalog is in the works, and there will be several new models for 2007.
Reciently a customer asked the difference between a Proto type and a regular nodel.

Prototypes are knives made in order to test the size and shape of a new design. They are fully working knives with the same fit, finish and functional reliability, and warranty as the model that follows them. When design changes and tests are complete, the model may be added to the catalog, and often will be renamed. These proto types are an excellent example of the design process, they are also very rare. ..

Once cataloged on my web site, the finalized design is made over and over again as many times as I get orders etc. The shape and size remain as close as possible to the finalized and cataloged design as possible..
 Easy enough, but a new design has certain cryteria to meet before it becomes a Relentless model. First it has to be useful, some shapes seem like a good idea, but after testing , prove to be less than they might be for a variety of reasons. The internals of the knives remain constant, but the size of a knife and the shape of a knife have everything to do with it's intended purpose.

I also make a few non cataloged items, Like the M1 Midget,and a few others. These are completed designs that for one reason or another never make it into the catalog, and are not available on an order basis. They appear from time to time on Ebay, or on my web site. They are great knives, and have been tested and approved for the catalog, but I can only make so many knives, so some just happen from time to time.
Finally I make Special editions, which are dressed existing models, usually to commemorate an event etc. These are listed on my web site and are available on an order basis.
The word proto is hand etched on the tang or blade of proto's.
Also, I am now in the process of up dating my catalog and web site for 2007 and the history pages will reflect previous models and makers marks etc.
Since I have photos of almost every knife I have ever made, it should be interesting. Also, since many of my customers are collectors, it will allow some to locate knives made years ago that are marked with makers marks other than the most farmiliar Relentless Knives.

ebay items We  working on the 2007 catalog,  that means there will be a few or more protos, non catalog items etc as the  knives are produced , tested , photographed etc.  Click the ebay icon to see what's for sale there.

I've designed a new knife sheath, that solves an old problem.
Here's Capt Humphreys report:

The New Relentless Knives/Spec Ops Brand Sheath/Pouch Combo
by: Capt. Ian Humphrey
How many times have you been frustrated with the lack of a decent sized

pocket on your knife sheath?  The new Relentless model sheath solves this
problem by combining an X2 multi-purpose pouch with a Kydex sheath to
securely hold your tactical fixed blade knife.  This combo will be available
in multiple colors to suit your needs.  This new pouch offers the same MOLLE
compliant straps that allow the pouch to be secured to a variety of surfaces
from vests to belts.  There is also an ample section of Velcro on the pouch
flap to adjust to different size loads, or to be securely held open for easy
     I tested the new pouch on a MOLLE vest and found that it quickly and
securely attached to the straps.  The Relentless M1i fit snuggly in the
Kydex insert and road securely behind the pouch.  Even with a fully loaded
pouch, the knife had no problems fitting into the sheath.  The main
advantage to this new combo pouch is the saved space on your vest, etc.
since you do not have to carry both a sheath and ammo pouch separately. 
Another advantage to this new combination is the fact that the knife is                               click here for more photos
almost completely hidden behind the pouch.  This could come in handy when
you do not want to advertise a large tactical knife on your person.  Besides
holding two M16 30 round magazines, I was also able to fit a Garmin Etrex
GPS, compact binoculars, GI issue angled flashlight, a ton of 550 cord,
Willey-X goggles, pocket survival kit, etc. etc. inside this one pouch (not
at the same time, of course!).
     Overall, I was very impressed with the new Relentless knife/pouch
combination.  For the first time you can receive a quality knife sheath that
includes a large enough pouch to store a variety of useful accessories.

UPDATE......!   The 7.5" sheath is now a reality. This means it fits the M9 Bayonet and many other blades up to 8" long.


           Special Thanks to Men of the 10th Mtn Div. in Iraq.
Warrant Officer  Lefebvre has a couple of these sheaths with him, and  will be sending us test reports and photos soon.  
                            Stay Tuned to the Enews.

We have received our first load of sheaths, and they are going fast. Colors thus far are ACU, Black and Coyote Brown.

Military Knife, and Gear Testing

 Don't get the idea that the U.S. Government has anything to do with our  tests.

No,  our knives etc. are tested by professional individual soldiers in their spare time,  so there's no politics involved here. We just want to make sure that the knives we  make , test, and sell meet or exceed  the needs of professional soldiers, policemen and adventurers.
Why?    We are Committed to Excellence! You won't find Relentless Knives everywhere, in fact, production is all by hand, and .......well it's a slow process to say the least.
But, well worth the time, as they are made to last a lifetime,
and endure the rigors of battle.



Understanding Serrations

 by: Capt. Ian Humphrey

     They say an old dog can not learn new tricks, but I beg to disagree.  I have been performing some tests on some new Relentless Knives models and commented to Dan that the small sections of serrations found on two of the knives did not cut very well.  Dan proceeded to explain the idea behind the serrations and how they should be used.  It turns out that I was trying to perform a “sawing motion” when I should have been trying a “scraping motion.”

     The serrations on the smaller models like the Talon, Midget, etc. are usually only three or four long.  The intended uses for the serrations are to cut 550 cord, strip electrical wire, notch wood, or make fuzz sticks.  These serrations are not designed to act like a saw to cut through tree limbs, etc. 

     The best technique to cut 550 cord or to strip wire is to anchor the material against something and pull it tight with your non-knife hand.  With the knife, place a single serration against the cord or wire and “scrape” the serration towards you (see pictures).  If the serrations do not initially cut, you can sharpen them with four or five strokes of a small carbide sharpening steel.  Once I got the hang of this new technique I was quickly able to severe 550 cord and strip wire with ease.

     The serrations can still be used to notch wood and create fuzz sticks.  By rapidly sawing on the branch, the serrations will make a nice notch to break off the branch or a fuzz stick for lighting fires, etc.


     The key to these serrations is that they are not meant to serve like a “serrated edge knife.”  Dan created these serrations to save the blade’s edge by allowing a specially designed area for cutting cord, wire, etc.  This saves the edge for other cutting tasks. 


Extreme Testing produces Extreme Durability and a better knife for you.

Don't try this with your knife, intentional destruction will void your lifetime replacement warranty.
But, we do it all the time in order to see just how
much abuse our knives will withstand.

Ian figures no amount of abuse is to much, so
a bit of rifle fire produced some interesting results on a knife that withstood bending to almost 90 degrees
and returned to straight with no deformity

The 7.62 x 39 Bullet had more devastating effects
on this particular knife, but was not so bad on another tested.

Watch for the complete report as well as other interesting articles in the test and review pages of

..Direct Hit. Ian hit this M4 Bounty  Hunter dead on with his AKM.
A small crack , but not bad for such abuse..
Please don't try this at home,  as gun fire will be considered extreme
abuse and void your lifetime warranty.
Ian doesn't seem to care....he is more concerned that American Soldiers who carry Relentless Knives get the best equipment available.

Watch for the Great American Steel test..
Ian Humphrey has taken variety of commonly
used knife steels and put them through a battery of  
tests to illustrate practical  expectations in the field..
It's and interesting and informative look at what you can expect from  the stuff your knife is made from.

To Kill an American
You probably missed it in the rush of news last week, but there was actually a report that someone in Pakistan had published in a newspaper an offer of a reward to anyone who killed an American, any American.
So an Australian dentist wrote an editorial the following day to let everyone know what an American is so they would know when they found one. (Good one, mate!!!!)
 An American is English, or French, or Italian, Irish, German, Spanish, Polish, Russian or Greek. An American may also be Canadian, Mexican, African, Indian, Chinese, Japanese, Korean, Australian, Iranian, Asian, or Arab, or Pakistani or Afghan.
An American may also be a Comanche, Cherokee, Osage, Blackfoot, Navaho, Apache, Seminole or one of the many other tribes known as Native Americans.
An American is Christian, or he could be Jewish, or Buddhist, or Muslim. In fact, there are more Muslims in America than in Afghanistan . The only difference is that in America they are free to worship as each of them chooses.
An American is also free to believe in no religion. For that he will answer only to God, not to the government, or to armed thugs claiming to speak for the government and for God.
An American lives in the most prosperous land in the history of the world. The root of that prosperity can be found in the Declaration of Independence , which recognizes the God given right of each person to the pursuit of happiness.
An American is generous. Americans have helped out just about every other nation in the world in their time of need, never asking a thing in return.
When Afghanistan was over-run by the Soviet army 20 years ago, Americans came with arms and supplies to enable the people to win back their country! As of the morning of September 11, Americans had given more than any other nation to the poor in Afghanistan.
Americans welcome the best of everything...the best products, the best books, the best music, the best food, the best services.
But they also welcome the least.
The national symbol of America , The Statue of Liberty , welcomes your tired and your poor, the wretched refuse of your teeming shores, the homeless, tempest tossed. These in fact are the people who built America .
Some of them were working in the Twin Towers the morning of September 11, 2001 earning a better life for their families. It's been told that the World Trade Center victims were from at least 30 different countries, cultures, and first languages, including those that aided and abetted the terrorists.
So you can try to kill an American if you must. Hitler did. So did General Tojo, and Stalin, and Mao Tse-Tung, and other blood-thirsty tyrants in the world. But, in doing so you would just be killing yourself. Because Americans are not a particular people from a particular place. They are the embodiment of the human spirit of freedom.
