I have a couple of German friends I got to know about ten years ago here in Québec City. They had a house here back then, and they had seen me making knives durind a one-man show in May in Old Québec. Here is one of the knives that they brought me for repairs...
As it was...
I had to saw off the copper ring on the guard and remove the old pin.
And then solder on a new guard, and install a ringed gidgee handle.
