Good subject Eric. I traded a guy in Germany a nice Heller SA for a Teno EM hewer and the blade was not magnetic and had no markings under the grip plates and was not numbered. It was Eickhorn. I was fortunate enough to get my SA back but the guy had buffed the blade and cleaned all the nicotine from the crossgaurds and scabbard fittings! Made me feel kind of sick when I got it back. Oh well, at least I got it back.
