Thought i'd ask for some simple info. I bought a cuda cu220 from ebay advertised as having ats-34 blade steel. Having never seen Camillus advertise this knife in this steel before I thought i'd grab it.The box has on it ATS-34 USA. Even though there is no marking on the blade,and it seems to be the 420hc model should I believe that it is ats-34? The knife is great just wanting to know!Thank's
