I want use my home workshop to rebuild an old, junked restroom from a
USAF DC9.

The milspec drawings show a slot for "used razor blades".

How often am I supposed to clean out the used razor blades to maintain
airworthiness specs?

Not to worry, Homeland Security won't allow razor blades in an aircraft
****ter, ground bound or not. BG
