A possible use for the tools found in the Somerton Man’s suitcase
“The tools used in stencilling and stencil cutting are few and simple. To take the cutting equipment first, one requires a good sheet of plate glass about two feet square, or larger, a stencil knife, and an oilstone.
As to the knife itself .. Almost any good blade of a shape readily capable of being sharpened to a point will serve as a stencil knife, and I have seen an excellent tool ground down from an ordinary table knife.”
