I was out at the lake and saw some rebar sticking out of an old silo. Lake was impounded in the 40's, so the silo has to be older than that, likely pre-depression if I had to guess. The rebar was twisted, like on an old wrought fence. Any ideas about what this might be useful for? Any historical period info on when twisted rebar was standard? Planning on taking the hacksaw next time I'm out and cutting off a bit, could be interesting blade or guard material.
