Hi,
There doesn't seem to be much interest in these rather scarce knives. I'm not really surprised as there is not many about and not much to go on regarding information on the internet or otherwise. I have added a few links to sold Eunjangdo from respected dealers for information and comparison.
Regards,
Norman.
