Mei on iron piece

[John C]

Hello:

Saw this mei on a decorated iron piece. Too short to be a bokuto "doctor's sword" but too long to be a netsuke. Not symetrical enough to be a tansu handle. 

Anyway, I was curious about the name of the metal smith, which may give a clue as to what it is.

I believe it is Nakajima Masayasu

“中島政安”, as Ray said!

Thanks, Ray and Uwe. All I could get was the Na at the beginning.
