I really enjoy making blades out of metals that are rusting away out in some farmers field. Kind of a spiritual thing, thinking about that steel that gets a new life and may travel the country strapped to the buyers side for the next forty years.
If anyone can relate and wants to experience the same joy, or even wants to make a blade for himself and enjoy the feeling many times over, I have found that the tines from the old spring plows, are something between 1080 and 1095. My Rockwell testing seems to indicate 1095. There are so many blades in just one tine, you will have steel enough for quite a while. Just FYI.
Ballbearing races are also an excellent source of an equally great alloy (52100) as long as you are sure that they are not stainless or high temp bearings (two additional alloys NOT useful as blades), but not nearly as nostalgic.
