There was a cold steel video promoting their tomahawks (I think it was cold steel at least). They were able to do some nasty stuff to a car with them. Though it was one of their own promo videos.

Hi Tengu, I don't know steel, but I do know some Chemistry: www.chemicalelements.com/Cr = Chromium Mo = Molybdenum V = Vanadium All three are metals that are used in varying degrees with Fe (Iron) to create steels with special properties. Usually the numbers refer to percentages or ratios. Try googling it with AISI. My Mom has a kitchen knife from Japan made with such an alloy, it is amazing sharp, but does need to be sharpened often.

Tengu
Personally, I would prefer a more standard high carbon for either of those two items, but on the other hand. SOG makes some great stuff.
They are indeed very popular with the military and I know quite a few firemen that trust them as well.

8Cr13MoV is a low carbide stainless steel that has similar properties to AUS-8. The chemical composition of this steel is as follows Steel type | 8Cr13MoV | HRC HARDNESS | 58-59 | CARBON | 0.80 | CHROMIUM | 13 | MANGANESE | 0.40 | MOLYBDENUM | 0.15 | NICKEL | 0.20 | PHOSPHORUS | 0.02 | SILICON | 0.50 | VANADIUM | 0.10 |
It's a good steel for that type of blade. I trust SOG and their decision to use this steel for that type of blade.

SOG makes good stuff, I have one of their first multi-tools from about 15 years ago, and have put it through the ringer many times. Nothing has snapped or broken on it, and it has not rusted at all. Despite being rained on, or falling/jumping into the river/lake while wearing it etc etc. My instinct tells me though that 420 might not be the "best" choice for something as large as that tamahawk, but probably not a "bad" choice.
