Gerber Hershey Hunters Fixed?

I just looked at the Gerber website, which describes them as 400 series surgical stainless, not a good sign. Probably indicates that its the 420 since there is a stigma against using it in what are supposed to be high quality knives. I think if it were 440 they would specifically say 440 series, not 400 series. Just my 2 cents worth on the matter.
