A larger, heavier hawk.
Specs.
Lenght - 16 inches.
Thickness - 5/16 inch
head length - 10 inches
Blade length - 3 1/2 inch
Weight - about 25 oz.
Steel
Single piece 40hnma steel.
40 HNMA is a aerospace grade steel, equivalent to 4340 according to AMS-6359 standard.
According to "Manufacturing technology for aerospace structural materials"
"The 4340 is the benchmark by which other high strength steels are judged. It combines deep hardenability with high strength, ductility, and toughness.
It combines deep hardenability, high strength, ductility, toughness. It also has good fatigue and creep resistance"
It can be harder, tougher and much more fatigue crack resistant than 4140.
Heat treatment
We used uniform multistep heat treatment.
Normalising
two grain refinement cycles,
quenching cycle
tempering cycle
Hawks are about 50-52 hrc.
Handle slabs CNC'd out of black paper micarta. Matte finish
Hawks are zinc coated for active rust protection
NO sheaths for this one.
Price - 135$ shipping included. Paypal invoice.
