Columbia Cutlery, Worchester, Mass - Grunge, Patina or Blueing?
Working slowly through a lot of grime, a small bit of corrosion and a pair of tiny rust spots on this unpitted Columbia Cutlery Co. razor the darkening was very uniform from toe to tang. The few Columbia (Worchester, MA) razor photos I find are restored and polished to the max.
Is this age staining or was it blued? Gun experts and I are not sure. FWIW, this razor was very slow to hone; seemed like chips took forever to get gone.
