Knives for Brave American soldiers


  Victory to the American Soldier!
God Bless the Republic!

People are  worried  about the economy, and about gun  and ammo bans.
And....we sincerely hope that all that drifts into history where it belongs.
But,  some financial experts  either full of gloom and doom, with physic powers
 or  more,  say that after a lull.....Hyper inflation will happen. Of course no one knows this for certain, and it can be simple hype.
But one might consider,
should such a thing happen,  products,  as they did in the 1970's could soar in price, shortages, the rule rather than the exception. And possibly worse. seems only prudent to  make sure  you own at least one good sturdy knife.  It can serve you in so many ways, and  life without a knife can be  more  difficult than one might expect.
Many people don't understand how important a good knife can be during times when
simple survival may be the order of the day.
If your  not used to using a knife often and for extended periods of time, for chores you may not expect, you may not realize  that the  average knife blade is actually quite delicate and will break rather easily.  Not because it's not well made, but because without special enhancement steel must be hard and brittle to cut.
This makes most knives,  an expendable resource.
Relentless Knives are built to withstand the extremes of hard and heavy use without breakage.
Their internal makeup allows the application of great lateral force coupled with
great edge holding ability.In a situation of no resupply,
your knife could become more valuable than a truck load of gold.
We are not attempting to stir up an already whipped up bowl of krap here.
Just thinking that in case you haven't already considered an extreme use knife.....
there may be no better time than NOW.

 What about Rust and Stain on High Carbon Steel knives   
                    CPM s30V High Performance Stainless Steel  is one answer........but
there are other alternatives

I purchased two of your high carbon steel custom knives about a year ago, and LOVE THEM!!! I just cannot keep the rust off of them, no matter how hard I try. Is there any way I can have you parkerize them for me? I just want to protect them with a more permanent solution.
Houston, Tx.    
    Hi: Yes I can parkerize your knives, it would cost $50.00 per knife with 4 week wait time.
Have you tried P.B. Blaster on them.      BLASTER STOPS RUST
It is sold in Auto parts stores, and works better than anything I have ever tried. It costs about $3.00 per can.
All High Carbon steel rusts, and Blaster penetrates the steel and reduces it quite a bit.
Parkerizing works better but costs more.
CPM s30V High Performance Stainless steel cuts longer is just as strong and doesn't rust.

Steel appears to be a solid material, but it actually has a surface full of microscopic pits and craters.
Water ,  combines with carbon dioxide in the air to form a weak carbonic acid that can easily penetrate the pores of the metal. This acid quickly acts to separate the iron from the other elements contained in the metal and change it to iron oxide(rust). Salt and other acids make the process happen more quickly.
Fingerprints contain  acids , salt. and moisture which cause rust. Blood, meat, vegetable matter , leather  all accelerate the formation of rust on uncoated or bare metal.
This process microscopically  happens almost instantly, and grows.
It can be easily stopped. with the application of oil  or other coatings that block out moisture and air.
Interestingly enough, a light surface rust , often known as stain, forms a natural barrier to air and a slight barrier against water, and will give the metal a  bit more protection against rust than bare metal. Bluing commonly found on firearms, is actually a controlled coating of what would quickly become rust in it's later stages.

So how do you stop rust.........................


Well, there are several different ways, all with trade offs

#1 P.B. Blaster.......commonly available in Auto Parts stores, this is a penetrating chemical, that enters the pours of the steel, and through a chemical reaction dissolves rust.
Careful maintenance with P.B. Blaster....that is keeping a Blaster soaked cloth handy at all times....and wiping the knife after use or handling works very well.  Knives wiped with Blaster will survive being submerged in water etc, so long as they are dried and Blastered afterward. In the field Blaster on steel wool will ignite with sparks from a metal match and makes great tinder for campfires too.

#2 Parkerizing.
Unlike other coatings...and much like Blaster, but far more permanent ....Parkerizing is a process
which penetrates the pours of the steel, and deposits a rustproof metal coating
which bonds to the steel.
Parkerizing is a very effective rust inhibitor. You can apply it at home with careful attention to directions

I will apply it for you for approx $50.00
Parkerizing still requires the metal to be coated with oil.
Parkerizing will wear with hard and heavy use.
Parkerizing will not protect the naked edge of the knife.,
but is a truly effective rust inhibitor, and rust will not creep up under
the coated part of the blade.

Dura Coat / Powder Coat and other coatings.
These coating vary in durability....but all are coatings.
On a knife made from high carbon steel, there is a risk, due the the need
of the edge to be exposed for rust to work it's way under the coating,
resulting in an intact coating, and rusted and weakened steel underneath.
Dura coat is a flexible coating and lessens the possibility of hidden rust as the surface will reveal the under, and  allow you to take action before any serious problems  develop.
                                                                    See out Dura Coat tests.

Below is an excerpt from an article by Major Humphrey on Rust.
The tests were very practical in nature,  and will give you an idea of what you might expect from High Carbon steel exposed to salt water etc.

 Rust Test
     I wanted to expand the rust tests to include the affects of salt water on the different steels.  This was a three part test that first included a simple area of the blade covered with plain water.  The second part of the test was a solution of Epsom salt and water on the blades, while the third part of the test consisted of a strong Kosher salt water solution on the knives. 
     The L6 model came in first during the basic water test with an easy to remove stain and no remaining marks.  The 5160 model finished second with an easily removed stain, but a small rust/dis colorization spot remaining.  For the Epsom Salt test, the 5160 model finished first with only a badly stained blade.  The L6 model not only had a badly stained blade, there appeared to be a thin layer of rust forming on the steel.  For the Kosher salt test, the L6 model came in first with easily removed surface rust and only a thick black stain remaining.  The 5160 blade also had easily removed surface rust, but with more staining than the L6 model.
     In comparison to the above steels, I tried the same three tests on the new s30v steel.  After all three tests, the s30v steel had no stains and no signs of rust on the steel.  Even after the Epsom salt and kosher salt left a sludge on the blade, they were easily removed and no damage appeared on the blade.

Next, a report from the Major on knives that were Bead blasted

For rust, the knives you sent all seemed to develop  spots from time to time...but no real rust yet...but I am very careful when it comes to post use cleaning and BP blasting.  I have never had any issues with the S30V...that stuff survived my sweat soaked water knife tests with no issues.  Some of my original Relentless neck knives with satin steel finish will spot, darken real easily...especially that one L6 model.  I know the spotting, staining is the pre-curser to rust...but with a little TLC and Blaster it seemed to do the trick.  As for leather sheaths...I never leave the knives in leather for an extended time...again for fear of staining the knives, so i have had no problems with them either.          

So.....The best thing to do if you are to busy to maintain your buy a stainless steel knife.
But.....keep in mind that all stainless steel is not alike, and the addition of chromium  to steel in the amounts that  effectively fight rust, and at a hardness needed for good edge holding can increase the brittleness of the steel.
For this reason .....I highly recommend CPMs30V with the proper heat treatment and tempering.,
for a Super strong knife with excellent edge holding abilitys.....
NOTE: without the proper heat treatment and tempering , these great propertys are not brought into play and varied reports on s30V steel abound.
 Also note 
All stainless steel alloys can rust, they are only rust resistant, not rust proof. As with plain high carbon steels, proper blade maintenance is needed, though not as much."

      Finally, hard and heavy use also prevents rust, as the regular removal and replacement of the knife from the sheath, as well as the abrasion
caused by the the cutting task  gives rust little or no chance to form.
  Relentless Knives are made to preform,
take them out of the drawer....put them on your belt, then make them earn their ke
They won't have time to waste away, but will be by your side, like a faithful companion....ready to help you and make your day easier.

tell him you saw it here first.

from our  customers:

Is the TOPS version of the M4X also Zone tempered, and of what steel is it?

The TOPs M4X is made from 1095 High Carbon steel,  and,
I have been told that they  have obtained some flexibility
through differential heat treatment of the blade. But NO it's not ZONE tempered.
Major Humphrey has tested one , finding it adequate for hundreds of cutting chores.
So, what I can tell you is that in a factory knife, the TOPs
is most probably a very durable knife.

                                               RELENTLESS KNIVES
But,  the type of durability that I get from Zone tempering, is very different from just a differential heat treatment. Very durable  is different than EXTREMELY durable
My goal is  a spring temper in the spine of the knife.
this allows  extreme (32000lbs per sq in lateral pressure without permanent deformation in 5160 steel) and less but practically comparable in s30V steel.
This is obtained through careful selection of steel, and then a painstaking hand done heat treating process that increases the price and the life of the knife considerably. It
also allows  for extreme edge holding ability  in s30V steel which makes your knife last far longer because you won't be sharpening it away.
And  Hand forging, and Triple thermo quench options  to the mix, and you have what might be termed a SUPER knife.

This is not magic, just  the science of metallurgy mixed with hours to  hard  work  bringing you a knife that will keep going long after a hundred others fail.
Further, in a knife made to  order , you get  many other assets that are just not available in a factory made, or semi factory made knife. Every part of a RELENTLESS knife is designed  and redesigned to take extreme abuse, and to fit you and the needs of your mission.  

Perhaps the best explanation is seen in many other tool descriptions.
Relentless Knives would be  in the category of  equipment intended for constant heavy industrial use.

Relentless Mini Knives: Don’t Let their Small Size Fool You!
by: Major  Ian Humphrey

    Dan has just added some new models to his catalog, along with a few catalog variants, that deserve some special attention.  The new category of “sub compact knives” is a great addition to Dan’s already extensive catalog.  I have always been a big fan of the small fixed blade design and find it is the perfect alternative to carrying a folder clipped to your pocket.  While I carry a larger fixed blade knife in the woods or during field exercises, around the house or in “garrison” environments a Relentless Mini is the perfect choice.
    Dan sent me three examples of his minis for test and evaluation.  The first was a pattern like the Talon model, the M2Sub compact.

Scaled down considerably, and to balance perfectly on one finger.  This knife is stainless  steel  for easy maintenance and features yellow G10 handles and red spacers.  I have to admit, this is a very nice looking knife and my wife has threatened to “borrow” it on several occasions.  The knife comes with a kydex sheath with grommets to allow for various carry methods.  My carry method of choice for this knife is using 550 cord to make two loops around the sheath.  The knife can then be carried horizontally on the front of my belt for instant access.  The small size and weight of the knife allows you to carry it in perfect comfort while maintaining instant access while standing or sitting. 
I have also carried this knife hanging inside my pocket by placing a slip ring through the bottom grommet and attaching it to a small carbiner.  This would also allow easy carry on a belt loop, pack strap, etc.  The knife is nice and sharp and the shape of the handle allows the knife to fit perfectly in your hand using your first two fingers.  The edge of the knife features Dan’s tri-symmetrical edge that allows for a very strong point and lateral strength.
    The second mini I tested is a needle tip pattern that was based on the World War II OSS thumb knives.  The blade is L6  steel and extremely sharp.  The knife features green canvas handles with red spacers and comes with a kydex sheath with multiple grommets.  My preferred carry option for this knife is “bandoleer style.”  This means you tie a length of 550 cords to the lanyard hole in the knife and the bottom grommet on the sheath.  You make the cord long enough so you can drape it over one shoulder and under the opposite shoulder.  This way the knife will hang in front of you ready for instant access.  When you draw the knife from the sheath, the knife will still be attached to the sheath with the cord (the sheath will now hang down at your side or back) and this will allow you to drop the knife if both hands are needed for a task and have it hang in front of you until needed again.  I like this method over “traditional” neck carry since there is no tell tale cord around your neck and there is no chance of becoming strangled by the cord wrapped around your neck. 
    The third mini I tested had a really unique pattern and non catalog item..  There are no handles on this model (made out of AT 34 steel) and the blade is only a little over an inch long.  The handle is slightly longer than the other two minis and fits very comfortably in the hand.    This knife came with a square kydex sheath with a grommet in each corner.  This knife has become my most used model and is carried on a daily basis inside my pocket.  The square sheath keeps the knife from falling over in my pocket so the handle is always facing up for easy access.  The knife is extremely comfortable to hold and is the perfect size for all the daily cutting tasks you find throughout the day (string, cord, tape, boxes, etc.).  I have attached a short 550 cord lanyard to the lanyard hole in the knife to help with gripping the knife and pulling it out of my pocket.  Dan sent me some glow in the dark powder that I mixed with epoxy and dipped the ends of the 550 cord lanyard into.  Now I have a glow in the dark capability that allows me to find the knife in the dark when it is sitting on my nightstand or dropped in the dark woods. 
    Dan’s new line of mini knives fill a critical gap when you want the strength and versatility of a fixed blade knife, but the inability to carry a large tactical knife
e strapped to your belt.  The minis are quicker to deploy then a folder and much stronger since they are all full tang, fixed blade knives.  Their small size and minimal weight allow them to be carried in countless ways and insure that they are always with you.   So don’t let their small size fool you…they are more than meets the eye!

Eagle sign
Relentless knives believes in the Protection and Defense of the Constitution of the United States of America 
By Peter Ferrara, an associate professor of law at the George Mason University School of Law.
September 25, 2001 9:20 a.m. National Review
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
