Not familiar with Cr scale? My scale is set up for "B" and "C". Is Cr a softness scale set up as a durometer scale reading? 420stainless always reaches a "C" scale even if below 30.
No, sorry, I was talking about 5Cr13 (or 5Cr15) steel. 420J2 (to my knowledge) maxes out at around 53-54 on the C scale. Plus, on super cheap knives like these, I wouldn't expect to see any steel taken to max. hardness. If you're getting 56 or 57, I think it's probably not 420J2 (or the Chinese equiv. 3Cr13) but something with a wee bit more carbon. 5Cr13/15 steel is still super cheap and apparently averages around 56HRC or so, which makes it a potential candidate. Total speculation on my part, of course. I guess it could just as easily be 8Cr13MoV with a softer heat treat.
