Rusty Shinto Wakizashi

Overall Condition: This blade is covered with rust.  The surface is rough, there doesn't appear to be any kizu but no guarantee.  The edge bites into brass and appears good except for a little chip in the boshi.  There is a silver foiled habaki that may be solid under the foil but it may only be good for the silver.  The habaki is rusted on and I don't want to destroy it taking it off.
