RE4 Pro no attache case run (handgun|knife only) 2-2

The cabin is (normally) a nightmare without a shotgun, but boy oh boy, I happened to see a cabin fight video featuring one of the single most beautiful strategies I've ever seen in this game. HUGE props to Big_Balled_Bill for this incredible strat, which I will probably use in every single run from now on.

The rules of the run (created by Torao) are extremely simple:
No opening the attache case for any reason. This means:
--Only stage healing items may be used
--Only the handgun and knife may be used
--No merchant, as these interactions force you to open the case
I'm also going to only save at the end of chapters. In addition, no deaths, resets, or exiting and reentering a room are allowed.
