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.

Performance  under extreme conditions are what Relentless knives are all about. Some
good examples of this are tests to see if the
blade could support the weight of a grown
individual, and how well a knife would serve as an
emergency rope anchor. Now you are probably asking why
the heck would anyone ever use a knife for these
tasks? Well, extreme   situations sometimes require uncommon solutions.  I used a sledge hammer to pound the knife
into a tree and stood on the top  edge of the blade. No movement at all. Next, I
hammered the knife into the tree at a 90 degree
angle to the ground and stood on the blade width
wise. This time the knife did flex but returned
true once I stepped off. And just for the heck
of it, I did the same test while standing on one
foot on the handle area of the knife. This caused
the most flex in the blade but again it returned
to normal once I stepped off.
Next I moved to the cliff and drove the
knife into the base of a tree and tied some nylon
rope around the handle. I was then able to lean out
over the ledge using an emergency rappel
technique. Again, the knife did bend a little, but it
returned to normal once I eased up on the rope.
The knife served as a very stable anchor for this
task. Why use a knife for a
rope anchor? A very real
example of this would be a Bush Pilot
plane crashes in the wilderness. Or just a hiker who has lost their way in unfamiliar trails.
You may
need your knife to act as a rope anchor as you
safely lower yourself to the ground, descend a rock
ledge, etc. After living in Alaska for three
years, I can remember several similar situations with
a plane crashing into the wilderness with
civilization many miles away.
The bottom line on all of these tests, and
many new ones in the future, is to ensure you are
getting the best tool for your money. While no
knife is indestructible, it is good to know that
Relentless knives withstand extreme abuse. Dan
will continue to develop new designs for
different applications, and I will continue to do my best
to ensure I abuse the knives so you don’t have
NOTE: Doing these tests is dangerous, we do not recommend that you try these applications at home,  Breakage of the knife under these and other situations could cause serious injury or death. Deliberate attempts to destroy your knife are considered extreme abuse and will void your lifetime replacement warranty. They are presented here simply to illustrate the strength built into each Relentless Knife. There is no magic involved . Modern steel, properly prepared is incredibly strong. with abilitys far exceeding the above..
The key word here is properly prepared, which takes considerable time and effort, something many today have long forgotten.

For the last past 30 years, the City of Hong Kong has maintained security at it's Kai Tak and Hong Kong International Airport
with a squad of highly trained  Police Officers dedicated  to keeping   Hong Kong
and it's visitors safe .
With 44.45 million passengers and 3.58 million tons of cargo per year, it's a big job.
Hong Kong , the most densely populated city in the world,  Ranked in a 2006 Cato Institute report as, #1 for economic freedom, followed by Singapore. New Zealand, Switzerland, and the United States tie for third.
Hong Kong also ranked first in “freedom to trade internationally” and second in “size of government,” “regulation of credit, labor and business” and “labor market regulations.”
Surprising since  in 1997 Hong Kong government changed hands from  UK, to Red China.

 I am working on NEW models for the 2008 catalog. You will see prototypes and catalog variants in the next few months as I prepare NEW and improved models for the catalog. Some present models will be canceled, some will be improved, and of course some will stay as the reliable and popular models they have been for years.

Candidates for 2008 Catalog


Not in our 2007 Catalog, this is a new combination of designs, that affords the protection of a short sword and performance jungle machete. It was thought that M4 Extreme might be extended, with the integral guard of the M1i, (see my web site catalog)allowing the knife to be tethered to the hand. This feature allows extreme hacking, and brush hogging without the fear of the knife slipping out of the hand and being dangerously propelled. This is a great knife for high adventure back packing, and expeditions into uncharted territories where trails have to be blazed rather than followed. The knife is light weight for it's size, and Zone tempered for incredible strength.

Overall length is approx 15 3/4", Blade 10 1/2" (measured from rear of guard) X 3/16" x 2"


M1 Map

This model was introduced in 2007 catalog
OAL approx. 10 " with Blade, measured from rear of the guard,

5 3/4" x 1/4" x 1 3/4"
It's a great medium sized knife with a blade under six inches.
The MAP knife will remain the Great Military Combat knife it has been.

M1 Interceptor

OAL approx. 11 1/2 " with Blade, measured
from rear of the guard, 7 " x 1/4" x 1 5/8"

 This knife is a variation of the
M1 Interceptor knife,available in my
2007 catalog. It has a
NEW handle shape for this model.

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                                     Tiananmen Square, Taiwan independence , Falun Gong                                      .
