All About Pocket Knives

I am not sure that "Sailors Jack" is the correct name for a knife with no Marlin spike but the Tin Opener blade is often seen on a Sailors Jack.
Help with proper names id always welcome.
Here are 2 old Camillus knives, 5" closed. Note the Ebony jack has the old 3 line stamp, no "USA". This marking pre dates the 4 line stamp.
I date these as being WW I era or earlier.

The one with out the spike looks almost new. Two good looking knives.

"The one with out the spike looks almost new"
The master blade has sample # in black on back side so the knife is close to the same as when it was completed. I cannot say "left the factory" because this might have been from the display in the Camillus factory lobby. (please correct if display was not in lobby)
