The rust does not look too bad... A couple places look worse than others.


Even dull rusted razors cut like heck so begin with
a cautious plan. One plan is to send it to
someone to do for you....

You can sand it with some 1000 or 2000 grit wet dry 3M paper
from the local handy man shop. Most auto stores have it
as do most small hardware stores.

Tear off a bit not quite as big as a match book cover
and then use something to protect your fingers fold the
paper over the spine and lightly sand pinching the
blade between your protected fingers.

Use some of those chop sticks from Chinese take out
to make a tool to work the corners.

Spray with WD-40 and finish sand... and hone it
up.

The rust near and on the edge bothers me but may
just be surface....

Some of the guys in the classified have a set
of buffers that would make quick work of the
problem... then they also have a big kit of
hones to get it shave ready again.

What state are the scales in?
