On the lines of the Japanese saw , but without the big bucks, put you blade in a regular hack saw so it cuts on the pull. Go slowly, use your thumb as a guide. Use a not too fine tooth blade. 32 per inch is way too fine. Maybe 18 to 24.
He that would make his own liberty secure, must guard even his enemy from oppression; for if he violates this duty, he establishes a precedent that will reach to himself.
