What do you guys do with your old dead straight razors?

If a nick is too big to re-hone out, if the blade is broken
or misshapen through wear, do you throw away,
or make some thing from it.

I was thinking of using a 'dremel' type cutting disk
on the edge and making a small pull type saw for modeling,
or something similar with an old razor I found that really is
too bad to restore, and wondered what you guys did with
your 'too far gone' razors.
