Oh absolutely. Yes, shin-gunto copy. Just was listed as kai-gunto, so that's how i referred to it. As you say an in hand inspection would show its a fake as long as you had some knowledge of the subject. Just noting new traps for us novice gunto-philes.
As for the rest, all have said it far better than i could. Learn learn learn, read read read, ask ask ask.
I just hope a bad experience hasn't burnt the fingers too badly.
