"Uvhash" Tactical Combat, Counterterrorism Knife
(Shadow Line)
All Matching in non-reflective flat black camouflage
This is a top-of-the-line,
extremely tough and ultimate
corrosion-resistant, wear-resistant knife: a tactical knife , sheath, and accessory package
that is simply the best made. The knife is a complete crossover
type, suitable for utility, rescue, and working tool applications. This package is comprehensive, sturdy, dependable, and useable. NO OTHER SOURCE
can supply what you see here, all finely handmade to work with your gear, your outing, your mission, and your
excursion, no matter the situation and exposure. This is simply
one of the very best tactical knives and kit
made today.
Thanks, A. H.!
Hi Jay,
I hope you’re doing well. I just wanted to let you know that I received the knife, and it’s
absolutely incredible – truly a masterpiece. Thank you for the care and craftsmanship you put into it.

Included:
The Knife
- Size: Length overall: 11.6" (29.5 cm), Blade Length:
6.25" (15.9 cm), Thickness:
0.153" (3.9 mm)
- Weight: 12.5 oz. (354 grams)
- Blade: ATS-34 High Molybdenum Martensitic Stainless Tool Steel, Hardened and Tempered, T4 Specialty Cryogenically treated to Rockwell C59, proprietary surface oxide treatment "Ghost Slate."
- Bolsters/Fittings: 304 High Nickel, High Chromium Austenitic Stainless Steel, proprietary surface oxide treatment "Ghost Slate."
- Handle: Gray and Black Micarta® Phenolic
- Type/Purpose/Origin:
The Uvhash is named for the early 20th century
horror/fiction/fantasy writer H. P. Lovecraft's blood-mad god of the
void. This is drop point tanto blade, extremely strong and tough, a
medium sized knife, a solid, thin and sharp tactical, combat, and
counterterrorism knife, made with the input of military and
counterterrorism professionals for their wear and use in combat. The
blade design considerations were for an evolved version of my most
popular PJLT that I create for USAF Pararescue professionals,
refined for assault and counterterrorism work.
- Blade Steel Alloy: The Uvhash blade is a special hypereutectoid, high alloy stainless tool steel,
ATS-34. This steel is
extremely high in molybdenum and chromium, and I call it a
"chrome-moly tool steel on steroids." First, the carbon in this steel
is extremely high at 1.25 percent, allowing significant development of
martensite and
forming of essential iron carbides. The second element is chromium, and at 14
percent, this is a true stainless steel with high corrosion
resistance. High chromium also helps create extremely
hard and durable chromium carbides adding to the wear resistance
and overall strength and stability of the steel alloy. The third and most transformational element is
molybdenum. ATS-34
has 4% molybdenum, providing a high concentration of
molybdenum carbide particles, which are extremely wear-resistant
and contribute tremendously to toughness. Molybdenum is
a very important carbide-former, and it helps precipitate
carbides at critical dislocation and grain boundary areas of the
crystalline structure, stabilizing the structure against
fracture, toughening it. Toughness is
resistance to breakage, and since this is dramatically increased
in this high molybdenum steel, it allows a very thin cutting
edge and blade geometry with good strength. This means a
thinner, sharper, tough,
corrosion-resistant blade is possible with this steel.
- Heat Treatment: This Uvhash has my
T4 heat treatment, yielding an astounding blade in incredible
condition through advanced processing protocols. How advanced is
this treatment? It's a multi-stage cryogenic treatment,
involving temperatures ranging in over 2000°F (1090°C)
to -320°F (-196°C). The process is an evolution of my
advanced heat treating processes, and consists of 33 dedicated
and specific steps and takes 172 hours! This means that just to
heat treat this blade takes over a week! The reason for this is
scientific and critical, but yields the most stable, most
wear-resistant, most durable and long-lived structure of this
steel, profuse with fine multi-element carbides and a uniform
and unbelievably robust structure. This is a testament to my
determination to make the very best knives, steels, treatments
and kits in the modern world. I know of no one else who has
advanced the treatment to this level; it's unheard of in the
metals and knifemaking field.

- Blade Design and Geometry: This blade is
extremely thin for a tactical knife. Usually, most tactical knives
are fairly thick, but be sure to notice the specs on this one. What
you achieve with a thin blade is low angle geometry, a very thin,
precise and incredibly sharp blade. Combine that thin hollow
grind with the narrow angle of the point and I don't think you'll
find any other more aggressive needle-like penetrating point. The
Uvhash blade has a three-quarter length top swage that reduces the
thickness of the spine without sacrificing spine strength, and the
blade has 2.25" (5.7 cm) of my aggressive and popular
hammerhead serrations for tough cutting and ripping needs.
It is a true tanto, with a good length of straight cutting edge, and
a solid secondary point (yokote) for bearing down in heavy
applications without using the main point. The knife has a razor
keen cutting single bevel cutting edge with very light weight. The
knife is full tang, one solid piece of steel from tip to butt,
- Blade Finish: The blade and bolsters (and
all of the accessories) are in my "Shadow" line of
counterterrorism and tactical knife finishes. Answering the
request for completely subdued and non-reflective surfaces, I
developed the Shadow Line with my Ghost Slate finish. This means
darkening in a permanent fashion not only the stainless steel of
the knife, blade, handle, and fittings, but all of the gear in
the entire kit: the fasteners, the sheath parts, aluminum
mounts, accessories and entire package. Read more about my
Shadow Line and Ghost Slate finish on my Counterterrorism Knives
page
at this bookmark.
- This is a very thin and light tactical knife, with
an extremely keen stainless steel blade
with advanced heat treatment.
- Bolsters: I bolstered the Uvhash with my
signature zero-care, high nickel, high chromium 304 austenitic stainless steel bolsters,
contoured and rounded for comfort of the hands, and shaped and
radiused in the front face for easy cleaning. They are attached
with multiple through-tang pins of 304 stainless steel, and
the mounting is permanent, as well as extremely corrosion resistant. This is the
same steel used for stainless steel nuts, bolts, and fasteners,
and the bolsters are heavy, thick, and solid, giving great
balance to the knife. The front bolster is large enough
to support the massive quillon, offering a place to apply pressure
to the blade, and protecting the hand from sliding forward. The rear bolster has a
large chamfered 3/8" (9.5 mm) through-tang lanyard
hole for added security when working elevated or over
water or in a debris field. This large lanyard hole
allows fast and easy threading and hitching of
lanyards of any type. The rear bolster supports a handle
"hawk's bill" that locks the hand into the handle and offers good
counterbalance for the heavy blade. The bolsters are dovetailed to create a
solid, seamless union with the handle material. The bolsters are treated in my "Ghost Slate"
shadow line for reduced glare and match the rest of the knife
and gear.
- Handle: Zero-care
is important in the tactical knife and this Uvhash is handled with
gray and black layered Micarta® phenolic, a classic and durable
knife handle material. This material
is extremely durable,
complimenting the Ghost Slate darkened finish of the piece. The handle scales are secured with
four 1/8" through-tang 304 stainless steel pins. The
scales
are bedded to the tang and locked under the bolster dovetails. This is
a very tough material,
durable, waterproof, with a toothy textured surface that grips the
hand and requires no maintenance. The shape of the handle is
features some advanced concepts. The front quillon is extremely
large and robust. This provides great grip security and
protection for the forefinger, and it's contoured, rounded and
smoothed for comfort. The finger groove is deep and the
forefinger bears down on the bolster. Above the forefinger
placement is a thumb rise, supported by the wide bolster
so the thumb can apply great pressure. This also offers the notch
geometry for the locking sheath (described below). The Uvhash has a large, multi-finger
groove inside the tang for a comfortable, variable grip. The
tang is fully tapered with light and narrow alternating filework working
well with the handle pattern and adding handmade distinction.
- Balance and Feel: The angular tanto blade, the
lightweight spine and overall feel of this knife is very fast and
light. It's like a tactical straight razor with a needle point.
It feels quick and smooth in the hand, with
the balance point exactly at the forefinger placement.
