I would not call him a metallurgist but this guy has tested a bunch of steels using an unscientific rope cut test and documented them in a spreadsheet. He was the first one that convinced me to spend over $100 for a cpm-s30v knife and it was way better then anything I had before in edge retention.
His data cant be that bad though because I built a model to predict the number of cuts for a blade using edge angle and metal compounds (no real way to take into account heat treat though). It was relatively accurate for the less exotic steels. I should really share that with the world.

He also records videos of himself and posts them to his youtube channel along with other knife reviews.
