 About RELENTLESS KNIVES
RELENTLESS KNIVES  are made with the military in mind, offering  you a knife that is as flexible and durable as possible in a variety of ways.   We  want to make sure that  RELENTLESS knives 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  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.
 I use  materials and  processes that are expressly intended to resist  extreme abuse, and  have  invested a lot of time and effort  in testing the products myself.  Then I have them tested further by objective individuals in a sincere effort to bring you a product that is strong and reliable.
In today's world, this is rare.
Each RELENTLESS  KNIFE is  handmade by me in my shop. Unlike factory or semi production knives, each knife receives full  personal attention. One of the biggest drawbacks is wait time.  Our world is getting faster and faster.  We want what we want, and NOW! This leaves individual craftsman in the dust , as some processes  simply cannot be economically automated  and retain the enhancements they provide. Considering that with bit of care, the finished product can last for centuries, waiting for it might be easier.  Your order   receives unequaled attention to detail in every aspect of the production process. I take great pride in my work, and want your knife to be the best it can be.  I am not the judge of whether or not my work is good. I have hundreds of happy customers and unsolicited testimonials . Check out my feedback.   I work hard for it and am very proud to have you as my customer. The RELENTLESS spirit
that propels many to excellence is built into each of my knives.  You'll feel it as you hold the knife, and it will be with you so long as you own your
RELENTLESS KNIFE.

  SPECIAL EDITIONS

       An event, happening, anniversary and more can lead to a  Relentless Knives Special Edition.
They are usually cataloged models with special
cosmetic enhancements 
Prices vary, but these models, allow collectors to acquire some very special knives that could increase in value as the years go on.  Should your collection be pressed into service....not a problem, as all Relentless knives are built for a lifetime of hard and heavy use and carry a lifetime replacement warranty.





Features and Benefits:: Special Editions don't happen often, so read the Relentless Knives Enews for announcements.

Variants and Non Cataloged items  
Creative residuals: In the process of designing New, more effective models, the
  morphing process, results in first variants and then prototypes. The differences are strictly cosmetic, often very interesting
and in the scheme of things, quite rare.


Also, non catalog items are knives or other items that have not yet been added to this catalog for one reason or another. They are  often fully developed models that either missed the catalog dead line, or were in line with lots of other great knives and just could not get  a
space of their own yet. Or, were part of a design project that was interrupted  and for one reason or another not yet completed.


The sale of these  often fund the development project of new and better models. Collectors who are interested in this type of knife can find them on the available knives page from time to time under the title of Variant or when a development project in underway,
as prototypes. 
Features and Benefits: You will get a top quality knife that carries the Relentless lifetime warranty, but it will mostly be either a one of a kind variation, or a knife that is part of a development project targeted for a New model. For those who collect knives, these can eventually become very valuable.

 
With no options, each Relentless Knife is Zone Tempered, a process used by Japanese Samurai sword makers for thousands of years, which results in a super strong blade, with spring temper in the spine and 58rc hardness on the cutting edge. This gives you a knife that resists breakage even with the application of great lateral forces,that will hold an edge well, and re sharpen easily.
The Zone tempered knife is super strong, and will handle the most extreme conditions with ease.
But..... for the most demanding of customers
further enhancements are available,termed
HOT ENHANCEMENT which include hand forging,  triple thermo

cycled, quenched then Cryogenic treatment, followed by triple tempering.
Our goal ...... BRUTALLY EXTREME functional reliability.

The RELENTLESS spirit
that propels many to excellence is built into each of my knives. You'll feel it as you hold the knife, and it will be with you, so long as you own your
RELENTLESS KNIFE.

Wait time and ordering
You can order most knives on this site with 16 week wait time,
(standard  no options ) .
This is different than many custom makers, because, when my 16 week quota is filled, I will  not accept further orders.  The result.....Your knife in your hand 16 weeks or less.
Terms of sale are
listed below
Lifetime Replacement Warranty
You have a LIFE TIME replacement warranty against breakage except for extreme abuse and handles. Which means, I make the knives out of materials and with processes that are expressly intended to resist the rigors of hard use and, I abuse each knife before it is finally finished in order to make sure of it's strength.  This does not mean the knife is unbreakable, but it does mean that by human force alone, it is  rather difficult to break. So, I consider extreme abuse, a deliberate attempt to destroy the knife. In these cases,  have fun and let me know what happens, as this is beyond your warranty.  .........i.e. it will melt if you place it near a burning phosphorus grenade or repeatedly pound the handles with a ten pound sledge etc. etc.
Other than the above,  it's simple, just return the broken knife and I'll make you another without delay. Shipping not included.

Steel Selection:
All Relentless knives are ZONE tempered.  Zone tempering slightly reduces rust resistance so it is recommended that the knife be kept clean and dry with a light coating of any oil or rust inhibitor. This process greatly enhances the excellent properties of the steels  selected for their strength and durability
5160 (most economical) is a very strong steel so your knife will never break, but it rusts easily and requires frequent sharpening.
8670M/L6 Slightly less toughness than 5160 with twice the edge holding ability.  More economical than CPM steels.  Non Stainless. Very difficult to  break, even under the most extreme conditions.
 CPM S30V Excellent resistance to lateral force.  Superior edge holding ability greatly reducing the chore of sharpening, and wearing away of the knife.  Also stainless and resists rust unless exposed to salt water without rinse for 2 days.
CPM S35V High performance stainless steel.  Improved s30V formula offers you a better finish with more strength and ability to resist lateral force.  It sharpens easily compared to most steel with extreme edge holding ability.  It resists rust and corrosion far better than most stainless steels, although more expensive.  It is the best choice for a stainless extreme use knife available today.

CPM 3V SUPER High performance Semi stainless steel.  Super performance with strength far exceeding all of the above.  More expensive due to its difficulty to work with, but completely worth the extra price for a knife that will endure brutally extreme conditions.

is also available see our steel chart here

OPTIONAL: Hot Enhancement = Hand Forged, Triple Thermo Quenched, Cryogenic Freeze, Triple tempered.  Hot Enhancement turns an industrial strength tool into a super knife enhancing the breakage resistance and edge holding x 4.  These enhancements are for the most demanding users.  In practicality, you won't need them unless you plan on building cities in the jungle with your knife as your only tool.

I also work in other steels, and can make your knife out of anything you want within reason.
Prices and warranty will vary with other materials, as I have tested the above and have found them the best for the type of knives produced.
 ZONE tempered for incredible strength.
 Zone Tempering, a process used by Japanese Samurai sword makers for thousands of years, results in a super strong blade, with spring temper in the spine and 58rc hardness on the cutting edge, This gives you a knife that resists breakage even with the application of great lateral

forces, that will hold an edge well, and re sharpen easily.  With the advent of this catalog, Zone tempering  is now a stock enhancement on every Relentless knife
NOTE: Zone Tempering results in a softer steel in certain places, which reacts differently
with the bead blasted finishs than the harder areas, and produces a different color of gray in these areas. I don't ZONE temper for an artistic looking temper line etc, it is there for strength.
If you don't want the knife zone tempered, let me know and I won't do it to your knife.....sometimes it looks better, but I don't warranty non  zone tempered knives against breakage.
