1080!

When Camillus closed up shop Cold Steel changed their some of their Carbon V range (0170-6) over to SK-5 which given the blades are made in China I presume its a Chinese designation.

SK-5 is not a Chinese Steel.

It is a Common Carbon Steel that is used for Spings and makes a very Good knife.

I have used it myself in the past and it is close to 1080.

The Average user will not notice much difference between SK-5 and I095

Performance will all depend on the Heat Treat and the Goemetry.

It is usualy a japanese steel .

I remember my long lost Cold Steel Bushman was made from SK-5. It had a Rc. of 54 or something so that it could be sharpened easy in the field as well be used as a spear without risk of breaking.

I lost it in a move, I really thought it was neat concept and was inexpensive. I should buy me another one of those if you can still find them.

They must have wanted the extra Toughness at 54.

The Steel takes 58-59 without a pause.

Good Stuff.

SK-5 is the Japanese equivalent of American 1080, a high carbon steel with carbon between 0.75%-0.85% and 0.60%-0.90% manganese. As quenched, it has a hardness near Rc 65 and produces a mixture of carbon rich martensite with some small un-dissolved carbides. The excess carbide increases abrasion resistance and allows the steel to achieve an ideal balance of very good blade toughness with superior edge holding ability. Due to these characteristics, this grade of steel has been used traditionally for making a variety of hand tools, including chisels and woodcutting saws, and has stood the test of time and use over many years in many countries. Commonly, working temper for these SK-5 steel knives are RC 57-58.
