 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 todays world, this is rare.
Each RELENTLESS  KNIFE is 100% 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.

Features and Benefits  Custom work,  means I will tailor an existing model to fit your intended purpose, or can make a knife to your spec's. There are a wide variety of blade steels, handle materials etc not listed in the catalog.
This service takes considerable time, and is more expensive than a cataloged knife order , but the extra time and money will give you a knife that is not only strong, but well dressed .
The process often involves shopping for exotic woods , ivory, pearl or other handle material, so your patience and understanding  on time is a strict requirement here.
These projects are never rushed,  and the end result is very often a work of art.

  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 and are available for one year after their announcement.
Prices vary, but are often very close to the price of the regular model, which allows 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. And the Special Editions page of this site.
Also check the history  pages of the web site for information on previously issued knives.  Note: The history section of
the website is still under construction.
But can be accessed by using the little radio on many pages.                                                                         
            Soon, it will reflect  over ten years of knife making history, makers marks, etc   in an effort to assist many of my great customers in their wonderful hobby of knife collecting.

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 here  or on Ebay from time to time under the title of Variant or when a development project in underway,
as prototypes. These knives are marked as such, with the word Prototype or with a capitol V for Variant.
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 resharpen easily.
The Zone tempered knife is super strong, and will handle the most extreme conditions with ease.
But..... for the most demanding of customers
futher enhancements are available which include hand forging,  tripple thermo
cycled, quenched then Cryogenic treatment, followed by tripple tempering.
Our goal ...... 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.
 
Each Relentless knife comes with an  LB1 handmade leather sheath
pictured below, click the photo for a better look.
Optional sheaths of many configurations are available so check out our sheath shop for carry options and prices.

 LB1 shown to the right
features Black anodized Mil spec grommets 
which allow hundreds of carry options. 
This  slimline sheath, handmade from top grain  leather
has a slim profile  allowing you to
carry the knife in many positions. Visit our sheath shop for optional sheaths, ordering instructions and more.

in what you are paying for.
 PayPal or Credit Card it's fast, free and secure! 

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.

  Ebay
I want it NOW!
I understand, and feel that way too. So, in an effort to fulfill  these requests, I make a certain number of RELENTLESS  knives and offer them for sale on Ebay. This allows those who simply cannot wait, to bid on and win these knives at auction. They are the same knives that you see on this site, the quality guarantee etc. is the same..
I have been doing this for about 5 years now, and have found it works quite well.
What about Ebay prices.........Actually, the Ebay format  on many occasions allows you to buy these knives at reduced prices. Auction prices are determined by the bidders. In other words, there are three different prices in the collectibles field. Retail, Wholesale, and Auction price.
When you win a knife at auction, there is a strong possibility that you got it at the  lowest available price. What about the critics of Ebay and the knives sold there.. I have read in  places, like, knife related discussion groups, forums , etc etc. that the knives for sale on Ebay are simply junk, and that Ebay should be avoided.
Well, it's true that there is a lot of junk for sale on Ebay, and every where else for that matter. It is also true that many of these commentators are owners of knife related enterprises, and they find Ebay to be  un wanted competition.
I  find the structured format of Ebay a great place  to sell knives. Their  system allows both buyer and seller a certain amount of protection as well as hardy feedback and security .
So if you want a RELENTLESS  knife and you can't or won't order one, watch for
Ebay id relentlessknives.
Since I do very little  selling at wholesale....i.e. products sold to dealers for resale. other options are discussed below.
How to Order:   Cataloged Relentless knives

you a price on the job.  Upon receipt of funds, I will complete your knife without delay. Note that custom orders take more time than cataloged items, and are more expensive, but for the person who wants a Super sturdy knife with cosmetic enhancements that make it a work of art I would be proud to work with you.
Important Note: I don't buy other peoples designs, so any knife I make can and will be made again at my whim. Should you have secret or original designs I respectfully request that you read the sentence above before contacting me.   Most likely I won't use your design ever again, but,  just in case, I would  rather save us both the trouble in advance.
Steel Selection:
5160 steel is a great super strong High Carbon alloy steel that provides reasonable cutting ability, resharpens quickly and easily and as produced by RELENTLESS KNIVES has extreme resistance to strong lateral forces.
It is great for a military combat knife that may be put to hundreds of tasks besides just cutting. 5160 steel will rust and stain if not cared for, but is very difficult to  break, even under the most extreme conditions.
 CPM S30V High performance stainless steel has all of the positives of 5160, with added cutting ability exceeding 10x of 5160. It sharpens easily compared to most steel with extreme edge
holding ability.  It resists rust and corrosion far better than most stainless steels, and
although more expensive, is the best choice for an extreme use knife available today.
8670M/L6 is also used from time to time but is only available in 3/16 " thickness.
It is a great high carbon tool steel with slightly improved edge holding over 5160.
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 resharpen 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.
