Nakamura AXIS Family
Product Review (submitted on October 13, 2017):
Bought it as my hard working knife, used it through years of daily carry, several countries and a week in salt water, it's been through it all. The spring got a bit rusty, and the mechanism gets tough when packed with mud and dust, but that's it. Bought with the M390, absolutely worth the money. Tested it and it surprisingly came out to a true 60 Rockwell. Harder steel stays sharp longer, but you have to be much more careful not to break it. The different steels don't mean anything unless you can sharpen properly. Very disappointed how the factory edge came, however, as this thing can hold an edge down to 17 degrees and when taken up to 80,000 grit stone, its a perfect mirror. Factory edge was put through a mediocre grinding wheel that totally ignored the best part of having a hard steel.
