I am trying to find out if the unmarked ones are old enough to be 1060 or if they just didnt mark the low carbon ones. I have a handful of spikes from a track that was abandoned back in the 50's and I think that these might make into blades but I havnt really had the time to play with them.
I might try a hawk if they dont harden enough for a blade but it is pretty far down on the list right now.
