What is Rockwell Hardness?
The hardness of steel or other metals is usually measured on a scale called the
"Rockwell Scale", this scale gives a number value to the hardness. This
number is preceded by the letters Rc (for example Rc58). High numbers indicate harder
material. If a knife is too "soft" meaning it has too low a Rockwell hardness,
it will probably not hold an edge and will bend quite easily. If a knife is too
"hard" meaning it has too high a Rockwell hardness, it will probably be
very brittle and difficult to re-sharpen. When a knife is designed, it is important
to determine from the beginning what kind of hardness will be required for its ultimate
purpose. This will affect the choice of steel. Once the steel is chosen, a heat
treatment sequence must be devised to result in the exact hardness needed in the
What is the difference between a Saber Grind and a Flat Grind?
is the most widely used edge configuration. It consists
of a final grind along the very edge of the primary grind. This final grind forms
the sharp edge of the knife. One of the main reasons for its popularity is that
the cantled edge is fairly simple to apply by hand or machine. It is also relatively
easy to control the angle of the cantle to achieve a desired degree of sturdiness
or fineness to the finished edge.
The Rolled Edge
has been in existence for over 1,000 years and
has been used by bladesmiths all around the world. But today it is qui te rare in
the knife industry. Some of the finest examples of this edge can be found on early
Japanese Katanas. It consists of a continuous curve from the primary grind right
to the edge of the knife. There is no "cantle" at the edge visible to
the naked eye. The only knife that Cold Steel currently makes with a rolled edge
is the Stainless Trail Master. A rolled edge is quite difficult to produce in custom
quantities and practically impossible in full scale production. The reason for this
is that it must be applied by hand, using a "slack belt". The honer must
constantly monitor his progress very carefully to develop a perfect rolled edge.
However, the result is a cutting edge that will easily outperform a standard cantled
edge, because it offers almost no friction during a cutting stroke. It slips effortlessly
through the cutting medium. Apart from the difficulty of manufacture, the drawbacks
to this type of edge are that it is typically very fine. This means that it is subject
to chipping if it comes in contact with very hard materials such as bone. It is
also difficult to re-sharpen by someone inexperienced with rolled edges. The only
recourse for this individual would be to send the knife back to Cold Steel for factory
resharpening or to develop a cantled edge in place of the original rolled edge.
Does Cold Steel in Germany re-sharpen knives?
No, at the moment we have no option or workshop for resharpening knives or swords.
What Angle are Cold Steel knives sharpened?
This question assumes that you are interested in resharpening a Cold Steel knife.
Our knives run a wide range of materials, grinds, types of edge and dimensions,
depending on the size, shape and ultimate purpose of the knife. So there is no single
edge bevel angle we can recommend. For example actual measured cantle angles for
various model Tantos are 25.79°, 30.99° and 28.157°. We suggest that you use whatever
angle most closely matches the one already established on the original factory edge.
Generally, we recommend 23° to 25° as a guiding standard.
How do you sharpen a Cold Steel knife?
The theory of sharpening is quite simple, although in practice it requires patience
and experience to become proficient. The basics are as follows: Start establishing
a cantle with an abrasive (stone, sanding belt, etc.). Then further define the cantle
by refining the scratch pattern with a series of progressively finer abrasives.
A good way to see whether your edge is almost done is to look for the burr that
forms along the edge and see if it is consistent all along the length of the edge.
Once you have a consistent burr, remove it with a finer abrasive or a strop and
your edge is finished.
For stainless steels:
If the edge requires repair (to remove chips
or dinks) or if the cantle has to be reestablished one should begin with a coarse
silicon carbide stone (Norton's Crystolon Bench Stone). Initial sharpening should
be done with a medium silicon carbide (Norton's Crystolon) or medium aluminum oxide
stone (Norton's India Stone). To further refine the edge a fine aluminum oxide stone
(Norton's India Stone) would be the next step, followed by a Soft Arkansas for final
sharpening. If an extremely refined edge is desired, follow the Soft Arkansas with
a Hard Arkansas or 6000-8000 grit Japanese Water Stone. Any ceramic system will
work if there is not going to be a lot of material to be removed along the edge
(the Sharpmaker by Spyderco is especially good for serrated models).
For carbon steels:
The same procedure as listed above will work
for carbon steels but we have had better results using only the Japanese water stones
(Japanese water stones can be found at most woodworking supply stores and catalogs).
We suggest beginning with an 800 or 1000 grit water stone and progressing through
a 1200-1400 grit and finishing with a 6000-8000 grit stone.
A rolled edge can be sharpened to its original configuration
by using a slack belt on a belt sander (320-400 grit belt) to get a consistent burr
and then polishing the burr off with a buffer or leather strop. One can also simply
redefine the edge by establishing a cantle on it as outlined above.
Can a false edge be sharpened?
Yes, all our blades which have a false edge can have that edge sharpened. This is
because the heat treatment is consistent throughout the blade. However, Cold Steel
will not sharpen the false edge on a Cold Steel knife, because of time and safety
Are Cold Steel knives guaranteed?
We stand behind our knives 100%. We subject them to the highest standards in the
industry and strive to make each one as perfect as possible. right now our return
rate for defects is one half of one percent! This is remarkably lower than the industry
standard. While we are growing in popularity, and producing ever larger quantities
of knives, we are determined to never forget that we live or die by a single word,
Our fixed blade sheath knives have a 5 year warranty to the original owner against
defects IN materials or workmanship. Our folding knives are likewise warranted for
1 year. If you ever have a warranty problem with one of our knives, please return
it with your original receipt and a short note and we will be happy to evaluate
the problem and resolve it.
(NOTE: Please remember ANY knife can be broken or damaged
if subjected to sufficient abuse and that ALL knives eventually wear out (just like
your boots) and must be replaced.
Are Cold Steel knives still guaranteed after they've been sharpened by someone other
than Cold Steel?
It depends. We have received knives back that have been almost totally destroyed
by resharpening on power grinders etc. In fact, some bear almost no resemblance
to their original shape! If the knife is damaged in this manner, by inexperienced
or overzealous resharpening, it will not be replaced, since this is not a defect
in materials or workmanship. However, if the knife fails structurally while in normal
use after it has been correctly resharpened, it is still covered by our warranty.
Do all Cold Steel knives have a full tang?
Full tang construction is an important consideration when evaluating the strength
of a knife. Originally, "full tang" meant a handle in which the edges
of the tang are visible all around the outside of the hilt, so that the tang is
fully as wide as the knife handle. However, with the advent of "driven-on"
Kraton® handles, full tang has come to mean that a very substantial tang extends
completely through the center of the handle right to the back of the pommel. This
describes the tangs on all premium Cold Steel knives.
How is Kraton® attached to the handles of Cold Steel knives?
To the best of our knowledge, Cold Steel was the first knife company in the U.S.
to use Kraton® for the handle of a knife. Obviously we were correct in our choice
of this material, because over the last 18 years almost every major manufacturer
has adopted it for knife handles. There are two main ways to build a Kraton® handle.
The first is to make a "driven-on" handle. This is where the Kraton® handle
is heated up to expand it slightly, then driven on top the tang of the blade. Once
in place it can be held there by a ferrule or a bolt.
The second method is to make a "shot-on" handle. In this type of construction,
the liquid Kraton® material is injected under heat and pressure around the tang
of the blade where it hardens. Once it has hardened it is permanently attached to
the tang and needs no bolts or a ferrule.
Did the Tanto really go through the car door?
Yes, this has been done in repeated tests without damage to the point. It has also
been done in "real life" situations where the Tanto was used to cut the
lock out of a car door to free a person trapped inside the vehicle. It is important
to note that the point of the Tanto is undamaged after this ordeal. Some people
discount this test because they say that some cheaper knives can also be hammered
through a car door. But what they fail to realize is that none of these cheaper
knives will have a usable point afterwards!
What is the maximum legal blade length that can be carried?
That depends on the blade configuration (single or double edged) and your local
laws. We cannot give a legal opinion. It is your responsibility to determine the
legal position in your own area.
What is "Blueing"?
Blueing is a process applied to the blade to offer a protective, less-reflective
coat. There are many commercially available packages for both hot and cold blueing.
The process results in a blue-black surface on the blade of the knife. It can be
quite difficult to get an even bluing over the whole blade. Cold steel does not
endorse or recommend this process yourself, instead you should have it done professionally
to achieve the best results. Also please see the next item.
Can Cold Steel knives be blued?
Yes, but this is extremely difficult with the stainless steel models. However, all
the carbon steel models can be either hot or cold blued. Please note that this blueing
may affect your warranty.
Can I leave my kitchen knives in the sink or in the dishwasher?
The short answer to this is no! Most stainless kitchen cutlery is made from high
chromium, low carbon steel. This makes it very "stainless", in that there
is no carbon to discolor, even if the knife is left soaking in water for weeks.
But it also means that it is practically impossible to sharpen to a good edge and
that whatever edge it has will be lost very quickly.
At Cold Steel we use very high carbon stainless steel for our kitchen knives. The
same steel, in fact, as in the Tanto. This allows us to create a blade that is very
thin and incredibly sharp, while still remaining very strong. Unfortunately the
trade-off means that the blade requires a little more care than some of your other
stainless cutlery. For example, it is not recommended that you use your Cold Steel
Kitchen Knives to saw through frozen food or to cut bones, as these actions will
surely damage your blade. These small shortcomings, however, are more than offset
by the phenomenal performance of the knives.
Although they will survive being in the dishwasher this is not recommended (apart
from potential staining, the fine edge can be easily damaged in contact with other
steel cutlery). They should never be left standing in water or left in damp conditions
for any length of time. To keep our kitchen knives in the best possible condition,
we recommend that the knives are rinsed in water, dried and put away immediately
after use, as with any fine cutlery. Any discoloration that may occur over time,
will not effect the performance of the knives.
Does Cold Steel ever make custom knives?
No, but there are hundreds of custom knifemakers in this country that would be glad
to make a knife to your exact specifications. Listings can be found in any of the
knife publications, forums or knifegroups at Facebook.
Do all Cold Steel knives come with a sheath?
Most of our fixed blade models come with sheaths; they are either made of Concealex,
Cor-Ex, or Leather.

What is the difference between the Emperor and Warrior Series swords?
We are aware that there are some people who want a battle ready sword but hope to
find one at a more reasonable price than our Emperor Series swords. Our Warrior
Series address this problem directly. In our efforts to reduce the costliness of
the blades, we have omitted the expensive mirror polishing that we used on the Emperor
swords and used a more practical finish. The Warrior Series shares the same steel,
heat treatment, and sharpness of their more expensive counterparts.
