Grafknives V-01C tomahawk
This time I have something black for you.
This tomahawk is a modern single piece interpretation inspired by classic design of Peter LaGana.
Specs.
Lenght - 15 inches.
Thickness - 5/16 inch
head length - 9 inches
Blade length - 3 1/2 inch
Weight - 21 oz.
Technology.
Steel
Single piece 40hnma steel.
40 HNMA is a aerospace grade steel, equivalent to 4340 according to AMS-6359 standard.
When comparing with 4340, 40hnma has lower amount of
sulphur - 0,030%
phosphorus - 0,030%
it gives the steel much better impact resistance.
But why we use 4340?
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 52-53 hrc.
Finish
Steel finish
Industrial black oxide.
In other hawks we use zinc coating, but it is too shiny.
That is why in this hawk I've decided to use black oxide, for a uniform black look.
Handle
Line-X - Industrial polyurethane coating.
This is high friction, pure polymer coating.
It gives thermal, electric and shock isolation.
Sheath
Two piece kydex sheath. I need about week to make sheath ready.

Warranty
I strongly believe my hawks are top notch.
Therefore I offer warranty against breakage.
If hawk will break when used or thrown it will be replaced by same or similar model of current production.
Sale
I have 5 hawks for sale right now.
Price is
