I have in the past accumulated a large collection of swords going back to C16th, sold some time ago to make way for a change of collecting direction. During the period I often looked towards Japanese metal, but never made the jump. Now, as a new entrant into the world of Nihonto, I am finding it fascinating. I have made made a few purchases,( including one likely mistake,) and plan to continue.
As I read more about age, makers and so forth, the award of Nbthk papers seems to offer some counter ballance for inexperience when spending the amounts of money involved. I understand now that other certificates are available, via London ( NTHK ) and USA ( choose desired certificate type ), and therefore probably other sources.
My obvious observation is how open to manipulation by market forces is the award of the certificates, ? and is there a common standard by which they awarded ?
Given how limited opportunities are to handle and compare, learning is slow, the number of unsigned blades is high, so, in reality reliable certification, or a dealers opinion seem to be the only real measure of reality.
I am, as you might understand from this, v. nervous about descriptions and values,
