STEEL
67
CARBON (C)
Increases edge retention and raises tensile strength.
Increases hardness and improves resistance to wear and
abrasion.
CHROMIUM (CR)
Increases hardenability, tensile strength and toughness.
Provides wear and corrosion resistance. Above 12% it yields
what is generally acknowledged as stainless steel.
COBALT (CO)
Increases strength and hardness, and permits quenching
in higher temperatures. Intensifies the individual effects of
other elements in more complex steels.
COPPER (CU)
Increases corrosion resistance.
MANGANESE (MN)
Increases hardenability, wear resistance and tensile
strength. Deoxidizes and degasifies to remove oxygen from
molten metal. In larger quantities, increases hardness and
brittleness.
MOLYBDENUM (MO)
Increases strength, hardenability and toughness of steel.
Improves machinability and resistance to corrosion. Pre-
vents high temperature creep. Helps retain fine grain size
and is an effective substitute for tungsten in many
high-speed tool steels.
NICKEL (NI)
Adds strength and toughness
NIOBIUM (NB) (colombuim)
Relative to knife blade applications, Niobium readily forms
NbC carbide within the microstructure which is an extremely
stable and hard form of metal carbide. Such carbides
provide excellent wear resistance and edge retention for a
blade application.
NITROGEN (N)
Used in place of carbon for the steel matrix. The nitrogen
atom will function in a similar manner to the carbon atom but
offers unusual advantages in corrosion resistance.
PHOSPHORUS (P)
Improves strength, machinability and hardness.
Creates brittleness in high concentration.
SILICON (SI)
Increases strength. Deoxidizes and degasifies to remove
oxygen from molten metal.
SULFUR (S)
Improves machinability when added in minute
quantities, but can decrease toughness.
TUNGSTEN (W)
Adds strength, toughness and improves
hardenability.
VANADIUM (V)
Increases strength wear resistance and increases toughness.
Limits grain size.

ASSIST BLADE
(Patented blunt tip) A hollow-ground blade with a blunt tip
designed to prevent accidental punctures. Designed for cutting
webbing, rope, seatbelts, or clothing.
BOWIE-SHAPED BLADE
Named after the legendary Colonel James Bowie, this term has
come to describe any number of variations of a blade with a
primary cutting edge with a curved “belly” and a clipped point.
The clip may be sharpened or unsharpened or may be straight
or concave.
DOUBLE-EDGED BLADE
A blade with sharpened edges on both the primary edge and
the spine or a symmetrical blade with two sharpened edges,
like a dagger.
DROP-POINT BLADE
A design popularized by the hunting knives of the late Bob
Loveless. The spine of the blade follows a subtle convex
arc to the point.
HAWKBILL BLADE
A sharply curved blade sharpened on the concave side.
Designed for cutting with a pulling stroke, it is commonly used
by commercial fishermen for cutting line, webbing and netting.
LEAF-SHAPED BLADE
A blade shape developed and refined by Spyderco. It is similar
to a spearpoint, but not completely symmetrical, and has a
more acute point and typically no swedge.
MODIFIED CLIP-POINT BLADE
A blade ground on the spine in an angled or sweeping line
downward to meet the point.
REVERSE “S” BLADE
A blade shape resembling a backwards letter “S” with the tip
curving downward and the widest portion of the blade curved
in a convex arc.
SHEEPFOOT BLADE
A blade with a blunt rounded tip and a straight cutting edge.
The lack of a traditional point reduces the chances of accidental
punctures around livestock, inflatable watercraft and during
emergency cutting.
SPEAR POINT BLADE
A symmetrical blade with an equal amount of curve on the
spine and the cutting edge. The grind line of the primary bevel
and the point both lie on the blade’s centerline. Spearpoint
blades often feature swedges or false edges on the back of the
blade.
WHARNCLIFFE BLADE
A blade shape in which the point of the knife tapers downward
from the spine to meet a straight cutting edge at the tip.
