LTK posted this video yesterday. If you don't already know, his channel has gone above and beyond standard knife reviews. He has gone to the trouble of having knives professionally tested, both for hardness and steel identity. Here, he shows and discusses some HRC results for popular production knives in M390. Do these results surprise you? Do they seem a tad low, much less for M390? What do you think is the ideal hardness for M390 and what seems to be the trouble here?
