  28. 440c hardness? |

    Somewhere in the 56-60 range from what i've seen,i think its x10 more important that the steel has a good heat treatment,Buck's 420 vs anything gerber (not the old Gerber,the new crap),i'd trust any Buck knife to do its job well because their heat treatment is amazing.Have a look at INFI by Busse,the steel composition isnt space age,but their heat treatment I think is around those lines.
