Request for Kozuka Assistance

[MasahigeDen]

Hello all, longtime reader, first time poster! 

I have here a kozuka I recently acquired with some shinshinto koshirae accompanying a pair of tanto. I am inexperienced with kozuka/kogatana, and any insight and/or translation assistance for this one would be greatly appreciated.

Much appreciated! I gather the early Ikkanshi Tadatsuna made some excellent blades, that focus seems to have been on a more mercantile clientele later in the Edo period, and that the brand still makes kitchen knives today. Do you know if there is a good way of dating a kozuka like this to a particular generation of the name?

Not that I know of. We usually caution people not to take too much stock in the names written on kogatana. It was common to engrave them with the names of well-known smiths, even if they had no connection to those smiths.

The general belief is that most of these were not made by the often famous sword maker whose name is on the blade.   I do wonder the how it came to pass that kogatana are so often signed with famous maker names.
