Hey, what steel did they use for the older Tigershark that was coated but had a non-serrated blade?

SK-5 carbon steel. n-i-c-e !!! very n-i-c-e !!!
Here's a tidbit from my old old archives:
SOG SK-5: "I've been told that the SK-5 we use (most likely a Japanese made steel) is very close to 0-1." -- Ron Andersen
O-1. This is a steel very popular with forgers, as it has the reputation for being "forgiving". It is an excellent steel, that takes and holds an edge superbly, and is very tough. It rusts easily, however. Randall Knives uses O-1, so does Mad Dog.
0-1 Properties
Carbon: .85-1.0
Maganese: 1.0-1.5
Chromium: 0.4-0.6
Nickel: 0.3
Vanadium: 0.3
Source: A.G. Russell Steel Chart
I will personally attest to the "take and hold an edge" characteristic. My SK-5 SOG's Tigershark and Bowie do exactly that: take and hold an awesome razor edge.
A couple of weeks ago a pal sent me a SOG Bowie to play around with, and that knife was even sharper than my own SOG Bowie. SK-5 definitely "takes and holds."
To keep rust/corrosion under control, I blued the blade of my Tigershark. And I ruined the bluing of my Bowie and now keep that bluing touched-up.
Cheers,
Carl

Wow. Thanks for the great answer.
The grey powdercoating will control rust, no?

I'm almost positive that if it's coated (even non-serrated), it's made of AUS6 stainless. If it is uncoated, it's SK-5 carbon.fulloflead said:Hey, what steel did they use for the older Tigershark that was coated but had a non-serrated blade?
There might be an old thread here in the SOG Forum where I specifically addressed this is more accurate detail. Look it up, if you wish.
