I am curious on information regarding old steels lets say western/frontier times to modern day steels such as 1075 or 1095. What I want to know is what steels were probably used back in those western/frontier days in terms of carbon steels. Would steels back then be more comparable to 1075 or 1095 in terms of strength/edge retention?. Also does anyone happen to know what steel the original Kephart knife was or what it is comparable to? Any information will be appreciated.
