Malcolm,

I've cut box joints by hand.  I found it to be very tedious, but it can be
done.  If the fingers are very small, it can really be tedious and the
fingers can be fragile so some amount of care is involved.  It really is
the same process as hand cut dovetails.  You mark it out, saw the sides,
then chisel out the waste.  Some people will saw out the majority of the
waste with a coping saw and then simply trim away with the chisel.  That is
my personal preference rather than chopping, but good work can be done
either way.  I assume the fingers will probably be 1/4" or less which means
you'll need a small chisel.  This also means that keeping the chisel square
will be a touch more difficult, but it can be done.
