I wouldn't want the best surgeon in the world using a clotheshanger and a steak knife, though.
I'd prefer that over being operated on by a monkey in a fully stocked OR.
The surgeon will probably know enough to correctly weigh the risk of doing surgery with poor tools against not doing surgery at all.
A surgeon with a steak knife is preferable to me with a scalpel but not a medical student with a scalpel.
But I guess the point is scalpels are usually easier to get then surgeons (or med students). And their quality scale is more finite.
