4x4 cross baton - 52100 edge stability experiments continued - Part 3

Continued testing of a new protocol intended to increase fine edge stability and consistency of my 52100, without decreasing toughness. This time, checking gross toughness doing a fairly unreasonable task (for a puukko) of hammering a pressure treated 4x4 in two (plus an old axe handle).
