Buderus 52100 - Experiments in increasing fine edge stability for my tools - Part 1

In an attempt to increase edge stability and consistency from my 52100 without drastically reducing toughness, I experimented with a few 'new' heat treat protocols. One in particular has shown the best edge stability I've seen thus far, with great consistency piece to piece. This is the first part of a series of tests I've ran to determine whether or not this protocol will end up being my new go-to.
