“Bristling with attachments, this new gadget is armament for assault on eight different kinds of containers.”

I have been doing a little searching around about the Pretorius 8 in 1 tool (with corkscrew of course) and had sent a couple of photo to Barry.  He asked if I had any idea as to a date for the piece.

With the graphics on the box, I assumed late 40’s early 50’s.

Well, wouldn’t  you know it, after a bit more searching around, I found an advertisement for the Pretorius:

Can Opener Does Eight Jobs.  Bristling with attachments, this new gadget is armament for assault on eight different kinds of containers.  It pries off caps and lids; it helps turn stubborn screw caps off all sizes; it shears off can tops; and it punches milk and beer cans. Priced at $2.95 by Pretorius Approved Products, Glendale, Calif.

Appearing in a 1950 issue of Popular Science Monthly, it seems like we can date the 8 in 1.  Why they opted to not mention the corkscrew is unknown.

Clearly that is the most important function…
