I do not know enough about the Krieghoffs to know what their base metal was for the frames. I know that at least some Perazzis were made of an alloy steel & heat treated & then given "Fake" colors. If an alloy steel such as this was given a traditional Case Hardening it would leave them excessively hard & brittle, could be the problem with the Krieghoffs.
