NBTHK help

Hello Group!

Can anyone help with the signature and comment given by NBTHK? I have been looking at this sword: http://nihontou.jp/choice03/toukenkobugu/katana/367/00.html

Sukenobu during kanbun I think but what is in parentheses and written in the next line?

Any other opinions on this sword are very welcome!

Ken
