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.

The difference between Bush Craft and Survival?
A survival situation usually ends when you are rescued.  So your task is to over come the environment hopefully for a short time, and usually without your u haul truck full of supplies.
Bush Craft is long term
survival, over coming your environment with
little or no equipment., and no foreseeable rescue. Either way,
a knife that resists breakage with good edge holding  and ability to adapt to a wide variety of tasks
could be your most valued companion.
Check out the Catalog and Details page for a variety of models, and details on steel, options, ordering instructions etc.

NOTE: Our Support Our Troops MAP program  is not ended.
We had a very large setback which through no fault of our own resulted in moving the shop and rebuilding from the ground up. So the program had  to be put on hold  for as long as it takes to fully recover which is still in the works, and moving along on schedule. Keep an eye on the Enews for Up Dates. And Thanks to Every Soldier who participated in the past.
In a situation of no re-supply,
your knife could become more valuable than a truck load of gold.

  In your experience,  would it be more ideal to purchase a steel such as cpm 530 v and apply a hot enhancement to increase the durability that is lacking in such a metal. In this sense I can save money from the lower price range of cpm 530v instead of s35v.  I am not aware of research comparing metals with hot enhancement Vs metals that are naturally robust but I would like to know if the H. E is supposed to increase strength x4 then, does that mean the cpm 530v becomes harder than cpm 3v ? If not then maybe I should opt for the steel cpm 3v,  without hot enhancement a difference in price from 399-559 equaling 159$ over the hot treatment for 225$. I hope this made sense to you.
Rob: In my opinion, You far better off choosing CPM 3V
I think your intended use of the knife has everything to do with the steel it is made from.
First consider, that the knives I make are intended for use by people who may find themselves in situations were their knife is the only thing separating them from great harm from environmental extremities.My primary intention is a knife that will not break, and then a knife that will cut.My thinking is your not cutting much with your shattered blade.Before the CPM steels, hardness meant more edge holding ability. It also meant brittleness and was just accepted. A knife with hardness of RC 60 cut real good for a long time, but
had little ability to withstand lateral force. The inverse, a rifle bayonet (RC52-55)could withstand great lateral force, but very little cutting ability. I started doing the process before the CPM steels were popular, on 5160 steel. That steel has huge break resistance, but not so much cutting ability. The process greatly helps that
giving you a knife with performance surpassing 01 in cutting ability
with lots more resilience. So then it was economically wise to choose enhanced 5160 over perhaps 440C or ATS 34.
Hot Enhancement is not about hardness, it is about reducing the size of the crystalline structure of the metal and then packing these crystals into a tighter package which
results in increased durability and cutting ability.

Once the CPM steels came along, the enhancement of 5160
became not such a need unless you really liked that steel.
The key to the CPM process is that the steel making process produces the same changes in the metal as does hand forging.
So the steel is already greatly improved over the non CPM steels.
Furthering this with my hot enhancement process improves it even farther

That being said each of the different steels have their natural properties and some are markedly better than others at certain tasks. If you look at the steel chart linked here, you will see the steels I use marked with green dots.  For instance s35V is Stainless
and cuts slightly longer than 3V, but it has less resistance to side loading than 3V which is semi stainless, but has incredible resistance to lateral force.

Hot Enhancement makes each of the steels better than before, but s30V will not surpass 3V in the above property, and 3V will not be stainless etc.etc.
You won't find much about Hot Enhancement of the CPM or other Particle Metalurgy steels, because almost no one does it. Why, because it is overly time consuming, tricky to do right, and, the results enhance the steel far beyond what the average person will ever need from a knife.  The key word here is(average person). As mentioned above if your job takes you to the extremes, then Hot Enhancement of any of the steels I offer will give you a knife that will endure great punishment and keep on going.
As it says in the explanation of Hot Enhancement, you won't need it unless your building cities in the jungle with your knife as your only tool. No joke.
So 3V is my is semi stainless, far better at rust resistance than any High Carbon tool steel like 01, D2,A2 etc etc and out cuts them for sure. It resists lateral force when prepared correctly to an unequaled extreme, and holds an edge just slightly less than s35V.
Yes it costs more, but is a life long investment in quality and durability that won't fail you.
