I’m currently visiting the San Antonio missions and have ran across a few things that I found quite interesting (and relevant here) to which the workers had no answer. (((I know, pictures are required and I will not disappoint))) So the question I posed to a park ranger (worker, in a national park) is this... with modern steels and modern forging, people oil quench to provide hardness. Were the tools on display hardened in any way or were they soft metals which would wear down quickly and bend easily? They provided only a blank stare, no answer. Also, if they were hardened... how did they do it?
