Bohler N680, is a highly corrosion resistant, fine grained steel, with high Chromium as well as Nitrogen, improving its corrosion resistance. It can be compared to H1 - it's not quite as corrosion resistant, but it is fairly close while holding a decent edge. It is imported from Austria.

0.54% Carbon (C), 17.30% Chromium (Cr), Manganese 0.40%, 1.1% Molybdenum (Mo), Nickel 0.50%, Nitrogen 0.20%, Silicon 0.45%, 0.10% Vanadium (V).


Bohler N690, the equivalent of 440F, which is 440C with a bit of Cobalt. Some compare it in performance to VG-10. It is imported from Austria.

1.07% Carbon (C), 17% Chromium (Cr), 1.5% Cobalt (Co), 1.1% Molybdenum (Mo), 0.1% Vanadium (V)


Bohler N695, is the equivalent of 440C. It is imported from Austria.

1.05% Carbon (C), 16.70% Chromium (Cr), 0.40% Managese (Mn), 1.1% Molybdenum (Mo), 0.40 Silicon (Si).


Nail Mark

A groove cut or pressed into the back of the blade for the thumb nail to easily open the knife.


Nail Pull

see Nail Mark


Navy, Ancient Knife

Large curved handle with a very blunt blade, could cut but not stab.


Adds strength and toughness. Expressed as NI.


Nickel Silver or German Silver

A alloy of copper, zinc and nickel.



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. Expressed as N.



The Latin name for the stone from which Arkansas Stones are cut. This stone is found in a wide range of density and ranges from very coarse to very very fine.
