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 I just thought I would write to let them know what an American is, so they would know when they found one.
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

Relentless Knives,have found their way all over the world.
In many places the term relentless
is more than a brand name on a knife.
Websters  Dictionary defines the term
re-lent-less; Unmoved by love or pity: Unceasing, as without mercy.  A tough word, for tough people, needing tough equipment.
Thanks to the men and women of the U.S. Armed Forces and others, for their relentless pursuit of protecting  freedom, and using
Relentless Knives to help them  along their way.

Like what if I had been doing the exact same job, but no tool shed was present, and what if I had only a pocket  knife with me at the time and had to build the fire to stay warm rather than burn wood scraps for cleanup.

Fact is that in that situation, my pocket knife would have been broken into pieces, and the wood would still  have been in it's original shape and size.
More thought brought me to the subject of convenience vs strength and utility.

For sure my OAL closed four inch tactical pocket knife, which opens up to a full and sturdy eight inch knife is  plenty strong and useful for many tasks. It is also far easier to carry than an 4 inch fixed blade knife  8  inch OAL. But, how  useful is it when your faced with uncommon situations were nothing else is available and the job is one where  failure results in devastating consequences like freezing to death etc.

In the above situation it boils down to four inches of steel separating you from a toasty warm camp fire or a  frozen death sleep. Sure you might say that the pocket knife correctly applied would do the job, and all would  be well.
OK no problem here, your mind is made up, your folder is in your pocket, ready to go without the inconvenience.

Better yet, your going to say that your well prepared with hatchet, axe, chainsaw and your backup Uhaul truck  full of supplies.
Again OK....your mind is made up. It is far more both convenient and effective to use the well selected, well  maintained tool for the job.

I say different. There are times when we are not afforded the luxury of everything being just so. There are times  when all you are or will ever be hinges on a simple singular tool that must perform without delay.

Those are the times for which Relentless Knives are made.
So large or small, you owe it to your self to have at least one and keep it handy.

Keeping your knife sharp
Many of you already know the following, but I get lots of inquiries from those that are unsure. To the knife efficianato this is old hat.  To those just starting in the  knife world, custom or otherwise,   it can be the difference between a long lasting partnership with an excellent tool  or lots of frustration.

Relentless M3 EXP
: Compact Protection You Can Take Anywhere
by:Lt Col Ian Humphrey
I also took the knife along for a winter hike and tested the blade on various types of hard and dry woods, and different types of rope and cord.  The shape of the blade made easy work of general cutting choirs but where the knife really excels is in stabbing drills.  This is in line with the classic tanto and Wakizashi design as an offensive fighting knife designed to quickly stab an opponent. 
     Dan continues to update his knife catalog and the ?Executive Protection? is yet another example of a solidly built knife designed for a lifetime of service.  Before Dan settles on a final design, he makes several prototypes to test different aspects of the blade.  In my case I tested a scaled down version of the knife that became a very handy every day carry knife whether on my belt or in my pocket.  I look forward to seeing how the full size knife compares in this classic design.

Relentless M3 EXP
The Relentless Executive Protection: Compact Protection You Can Take Anywhere
by:Lt Col Ian Humphrey
     Right before I deployed to Afghanistan, Dan Certo of Relentless Knives sent me a prototype of a new knife design he is working on.  This new model is called the Executive Protection EXP for short and features a classic design of a traditional tanto or Wakizashi (Japanese short sword) style of knife.  This design is eloquent in its simplicity and lends itself to easy carry and concealment possibilities"just what you need for last ditch "personal protection."
My test model was a scaled down size of what the final model will feature.  This prototype consisted of a three inch blade and around a three inch handle of tan micarta slabs.      
During my testing of this knife I carried it on a daily basis and used it to cut a multitude of everyday items like paper, cardboard, tape, rope, plastic, etc.
While this knife can ride on my belt with ease, I often found myself simply sticking the knife and sheath into my  pocket.  This enabled me to carry the knife discretely and still have it available for instant use.
Each Relentless knife is made from steels selected for resilience and strength and edge retention.
then Zone tempered giving your knife, far greater resistance to breakage than most knives.
Convenience vs Strength and Durability

Just a few days ago while working outside at the burn pit, I
needed to split some pine logs already cut to firewood size into
smaller pieces to get the fire going . The wood was semi wet, and not splitting easily.
I didn't have a hatchet handy, but did have a Relentless knife with 4" blade with me.

After about half an hour of bat toning I had reduced a few or more of these squatty logs into 1/4 inch kindling  that got the fire going real well.
For a baton I was using a thick pine stick, and with the wood being spongy it took repeated full power wacks on  the knife's spine to get it deep enough to then use the knife as a pry tool resulting in the wood separating itself  along the grain.
True if it had been hardwood like Oak,Locust, Walnut etc, the prying would have been un necessary as  hardwood splits far easier even when fresh cut, but pine is all I had, and the knife was also the only available  tool I had with me at the time.
Of course I could have walked the hundred yards or so back to the tool shed and retrieved a hatchet, or other  more appropriate tool, but in hindsight I wonder how much more or less work the hatchet would have been  given the sponginess of the wood. The prying motion of the knife I used was required to get the wood to split  down. Many knives would have snapped from the lateral force or the extreme pounding with the batton
The above experience led to my thoughts on how pine wood although it burns well when kiln dried is just not  as good a hardwood for fires. It also made me think of a few what if's.

Seems like every day I get questions on steel selection.

Here is the run down

CPM-3V  In my opinion this is the finest steel made for a hard use knife.
i have been making, testing and using knives made from this stuff for years  and am still amazed at the qualities.
Super Extreme Rugged dependability to put it mildly.  It is semi stainless so
unless you totally ignore maintenance for a long time it will not rust easily.
Break resistance far beyond all the other knife steels I have ever used , almost
unbreakable when properly prepared (ZONE tempered). Excellent edge retention and easy sharpening.

CPM-S35V Almost as good a CPM-3V and in some  areas a cut above.
It is a stainless steel, and although even fully stainless steel will rust if ignored, it has great resistance to rust and stain. Resistance to lateral force is far less than 3V
so keep this in mind when prying. Edge retention is better than CPM-3V but only by a few cuts. Sharpening is less painful than it's predecessor CPM-s30V and no edge chipping, a problem corrected by this steel which was previously s30V.

CPM-S30V. This steel broke the ice  being one of the first steels created by the crusible Particle metiliurgy process . I has served many far better then the older stainless steels like 440C and 154 cm. It is full stainless steel, far more break resistant than 440C etc. It's biggest drawback has been edge roughness in that
the edge of the s30V knife can and does develop microscopic chips on the edge which make the edge feel rough. This does not effect strength or durability, but
unless you polish the edge, which is often unmanageable in the field, your cutting
experience will be slightly saw like.

8670M/L6  If your budget is tight yet you need rugged dependability, this steel is just all that.
it has more than reasonable edge holding ability = to 1095 high carbon steel,
with break resistance far above most high carbon steels. It's biggest drawback is
resistance to rust and stain, so you have to keep it maintained with the same care you would give your blue steel rifle . Keep a light oil handy and don't store it in the leather sheath.I also often recommend coating the knife with KG Gun Kote, Dura Coat, Cerra Coat, Parkerizing or Bluing.  You can also simply spray paint the
knife with Valspar Clear, or Rustolium paint. i know it sounds po dunk, but,
realize that all coatings on knives wear quickly due to the nature of the tool.
It does it's work via abrasion.  So spray paint is quick and easy, and on most areas of the knife it will be rust and stain free for years.

5160 This is also a high carbon alloy steel, and reserved for those needing
high break resistance. It will rust and stain,  and it's edge retention is lacking unless the knife is forged, the triple quenched and triple tempered, then Zone tempered.
Before the CPM steels came about 5160 with the above hot enhancement
was great.  Without the Hot Enhancement, I believe it make good weaponry, but
unless you really love knife sharpening, 8670M/L6 is by far the better choice.

NOTE: I offer the above mentioned Hot Enhancement on all of the above steels which increases the durability break resistance and edge retention x 4
