CRKT Edgie

No, he's talking about the Edgie. The other knife is an obscenely overpriced Mitner-Adams, which also has a self-sharpening feature. I can't imagine anyone charging that much money for a knife when you can get a really great gun for the same price.

Lemme' get this straight. You paid $850 for a knife to cut cardboard and plastic strapping?:confused: Or are we still talking about the Edgie?

I suppose that could have been clearer, but yes, I am talking about the Edgie.
 
Because in the knife business, every steel is "high carbon" steel, even when it's low carbon! Cliff doesn't think CRKT's trying to deceive anyone, but as I look at CRKT's new and old catalogs, I see that every model that's changed has gone to a cheaper steel. Not one has gone to a better steel.

Not that the steel used originally was great. AUS 6 models tended to go to AUS 4 or 420j2, and many people don't care much for AUS 6. Oh, and I did notice that the prices didn't go down on any of the models. Imagine that!

Who do they think they're fooling by calling 420J2 "high carbon" steel?

It is a way of describing stainless steels that are hardened through heat treatment as opposed to those that are not, such as the stainless steel used to make kitchen sinks. All steel has carbon but "high carbon" steel refers to steels that have enough carbon that they can be hardened effectively through heat treatment. 420 is such a steel. It doesn't harden as much as VG-10, as an example, but it hardens more than a kitchen sink.

High carbon specifically refers to an amount of carbon, generally the exact amount that makes a steel high carbon varies, there is no rigerous and standard defination, but common ones are <0.2% low carbon, 0.2-0.5 medium carbon, >0.5 medium carbon. 420J2 is about 0.3% carbon. I have not seen a defination yet that would extend that low and still call it high carbon. Most will in fact demand significantly higher as 0.5% still isn't enough to reach full martensite hardness.
