So what’s it made of? Which blade steel is best? Just a couple of questions we are
asked when people see our knives, and the answers come down to this—Benchmade uses
a variety of modern materials specially selected for their superior performance
We strongly believe that if you’re going to put this much effort into designing
a custom quality cutting tool, then it only makes sense to build it of the materials
which complement its form and enhance its function. And in some instances it’s more
than just selecting a certain material, it’s what we do to it to bring out the extra
edge which sets us apart from everyone else. Bottom line, we would much rather overbuild
a knife than risk the alternative—we thought you would like that too.
Blade finishes refers to the surface treatment of the blade, which can be anything
from the way in which the steel is processed, to a multitude of blade coatings which
are applied to the blade itself. We use a variety of finish methods to "dress" our
SATIN FINISH: creates a low-luster sheen to the blade steel surface.
Several common forms of satin finish include:
- Stonewash: the blade surface is refined using abrasive tumbling media or
"stones" that leave a pronounced random "scratch pattern" on the blade. This finish
tends to mask any scratches that may occur with use. Examples- Model 805, 813
- Scotchbrite: this finish softly blends the grinding lines on the blade leaving
a pleasant "grained" or "brushed" look. Typically the graining pattern goes from
spine to edge. Examples- Model 190, 4530
- Tumbled or Vibed: similar to a stonewash finish; this finish leaves the blades
bright and smooth with a faint random scratch pattern. Examples- Griptilians, Bali-Songs
- Burnished: usually applied using non-abrasive media, whether by hand or in
vibratory equipment. This finish refines the blade surface without much of a discernable
graining or scratch pattern. Examples- Model 770, 941
- Hand rubbed: a finish typically done only by custom knife makers, it is similar
to a scotchbrite finish with the main exception being that the graining goes from
tang to tip.
POLISHED FINISH: can be defined as any highly-reflective or glossy finish
that refines and smoothes the metal surface. This finish aids in corrosion resistance
as microscopic peaks and valleys of the blade surface are smoothed out leaving less
surface area exposed.
BEAD BLAST FINISH: can be defined as any non-reflective finish applied to
the metal surface by bead blasting or sand blasting the blade with any of a variety
of media. The intent is to roughen the surface for anti-glare. The trade off is
it tends to be more susceptible to corrosion due to the increased surface area exposed.
This finish is also commonly referred to as a "military finish".
(Table of Common Steels)
When it comes to blade steels, Benchmade not only selects premium grades for their
natural qualities, but we also have perfected our own proprietary custom heat treat
process which maximizes each steel's edge toughness and cutting performance.
M390: A high performance blade steel with superior cutting ability
and wear resistance due to its high concentration of vanadium and chromium carbides.
Its unique powder metallurgical process also promotes a uniform carbide distribution
and clean steel properties, making M390 a popular steel used in surgical cutting
instruments and in applications requiring a high finish. As a blade material it
offers excellent corrosion resistance due to its high concentration of Chromium.
CPM-M4: Special purpose, high-speed steel with a combination of
high Carbon, Moly, Vanadium and Tungsten for excellent wear resistance and toughness.
A powder-metal, non stainless steel.
CPM-S30V: An American made and developed premium grade stainless steel
created especially for knives. It is a powder made steel with a uniform carbide
distribution and clean steel properties. As a blade material it offers excellent
corrosion resistance and superb edge qualities.
CPM-S90V: A unique tool steel, CPM-S90V is a martensitic stainless steel to which vanadium and carbon have been added for superior wear resistance. CPM-S90V offers substantial improvements in wear resistance over 440C and D2, and other high chromium steels, with corrosion resistance equal to or better than 440C.
154CM: An American made premium grade stainless steel originally
developed for tough industrial applications. Known for its best all-around qualities,
it offers great corrosion resistance with good toughness and edge quality.
D2: An air-hardened tool steel, which offers good corrosion resistance
and excellent mileage in wear resistance. A good choice for hard use applications.
N680: A chromium-molybdenum conventionally produced stainless steel
with the addition of vanadium and nitrogen. Excellent corrosion resistance properties,
especially in salt water. Good hardenability and high obtainable hardness. High
wear resistance and ability to preserve keenness.
440C: A high-chromium stainless steel with a terrific balance of
good hardness and corrosion resistance. 440C takes a nice edge and is fairly easy
to resharpen. An excellent value priced steel for its performance.
DAMASCUS: A specially forged, layered steel made up of a variety
of steels, It offers remarkable toughness and edge quality. For finishing, the surface
layers or lines are exposed through an acid etch, which creates a very unique visual
effect. Used in special applications due to its inherent high cost and artistic
CERAKOTE™: Designed and manufactured by NIC Industries, Cerakote™
has a unique ceramic structure that out-performs competitive coatings and improves
performance in both laboratory and real world settings.
BK1 ® COATING: BK1 coating is a matte black coating that provides
excellent corrosion protection, which exceeds the ASTM-117 spec for saltwater while
possessing higher scratch resistance.
BT2 ® COATING: A proprietary blade coating that is Xylan ® based
to provide excellent corrosion resistance which exceeds the ASTM-117 spec for saltwater
and increases overall surface lubricity.
BP1 COATING: Black Pearl (BP) is a PVD (physical vapor deposition)
coating made up of Titanium Carbo-Nitride (TiCN for short). It is a darker, near
black, scratch resistant coating with nice decorative qualities.
TANTO: Most tantos seen on the American cutlery market are Americanized
formats. Like the Japanese tanto, the Americanized tanto has a high point in-line
with the pivot. A flat grind is applied to the point, leaving it very thick and
extraordinarily strong. This thick area helps absorb the impact from piercing, as
the tanto was originally designed for armor piercing. The front edge meets the bottom
edge at an obtuse angle rather than curving to meet it as seen in the Japanese tanto.
The only negative aspect of the tanto blade shape is the cutting surface area is
sacrificed to gain tip strength.
DROP-POINT: A slow convex-curved drop in the point characterizes
a drop-point blade. This blade format lowers the point for control but adds strength
to the tip. It is a very popular blade shape that ranges from a slight drop to a
radical downward curve providing endless styles. In fixed blades this blades shape
easily sheaths. Usually coupled with plenty of belly for slicing, this format is
often used for hunting knives. Drop points are a great all-around blade format.
CLIP-POINT: A clip point is technically a variant of a drop point.
Instead of a “slow convex-curve” to lower the point; the profile is “clipped” to
bring the point down. Sometimes a concave curve will be referred to as a “clipped
point”. This is usually associated with bowie styles.
SHEEPSFOOT: This blade shape has no point on the tip, very little
to no belly and the spine of the blade curves down to meet the edge. It is used
in applications where slicing is the main requirement, and a point is either not
needed or would actively get in the way. Emergency rescue blades are usually of
this design. The lack of a point prevents the rescuer from inadvertently injuring
a victim who is being cut free from something restrictive.
Over the years we have developed a "special recipe" for heat-treating our blade
steels. This process maximizes the steels' molecular structure for a custom toughness
and Benchmade superior performance. All steels may be created equally, but that
is where it stops when it comes to making a Benchmade.

Benchmade takes care to design enough grip and stability in each model no matter
the overall size so that it will ultimately be functional to a broader range of
varying hands. The best way to test a handle for grip is to try it on and ask yourself,
does it feel secure, is it comfortable, will I be able to use it everyday if I need
When it comes to handle materials it's a matter of form and function. Whether it's
durability, weight, design style, or even price, Benchmade strives to select the
best material for the job.
