- Knife: Sadr (pronounced "sadder") is named for
a star in the constellation Cygnus, and is in a complex region of
the Milky Way, surrounded by reddish interstellar clouds, excited by
the glow of ultraviolet hot stars. Sadr lies at the center of the
constellation of the northern cross. This is a custom linerlock
folding knife, made for a great client. The blade is 440C high chromium martensitic
hypereutectoid stainless steel, and I've treated this blade for the
best possible condition with deep cryogenic processing, extended
time soak for maximum precipitation of sub-microscopic eta-carbides, followed by
triple tempering with deep cryogenic soaks in between for the
highest toughness, wear resistance, and highest corrosion
resistance possible in this steel. Every piece of hardware: the
pivots, the machine screws, the hidden and exposed parts are all
stainless steel or titanium, offering the highest strength and corrosion
resistance possible. The blade is mirror polished, with an accurate, serviceable hollow grind,
and a thin cutting edge backed up with plenty of spine for support. The
spacer-spine is also hardened, tempered, and cryogenically treated,
and is fully fileworked for handmade distinction, even on the inside
which is polished and finished. The knife is bolstered in
304 high chromium, high nickel austenitic stainless steel, for zero
care, and I hand-engraved a masculine, bold and deeply relieved
pattern to compliment the handsome handle scales and design. I made the liners
in 6AL4V high strength titanium alloy, and chemically anodized them
for a tough, wear and corrosion-resistant surface of deep blue, and
they are fully fileworked with a tight, close and meticulous pattern. The handle
scales are Biggs Jasper gemstone, a very tough, hard, and durable
gem of cryptocrystalline quartz, polished to a vitreous luster,
smooth and comfortable. The jasper has bold areas of browns in
layers almost like petrified wood, but with a few small areas of
white crystal. The gemstone scales are secured with bedding and
stainless steel machine screws for a permanent, solid fit. The knife
feels compact, dense, and tough in the hand; the lockup is secure
and tight; the detent pulling and holding the blade closed operates smoothly and evenly.
- Sheath: My client asked for a simple working sheath, so I made a
wet-formed pouch style sheath in 5-6 oz. thick leather shoulder,
hand-stitched with polyester and dyed a medium brown to match the
knife. The flap is secured with an all-stainless steel dot snap for
permanence and strength; the entire sheath is sealed with acrylic.
- A handsome knife, tough and beautiful in masculine form.
