O1 Steel – History, Properties, and How to Heat Treat

[Larrin]

New article on O1 where I tracked down where this steel came from (it was developed in 1905!). And a little about early use of O1 in knives. Also I compared the properties to other knife steels and some toughness data to figure out how to best heat treat the steel. https://knifesteelnerds.com/2019/08/26/o1-steel-history-properties-and-how-to-heat-treat/

Thanks Larrin. O1 was the first real (non reclaimed) steel I used starting out.
