Can you tell us more about the two knives that appear to be Japanese?

Cool photos.

It is the same knife, just the other side of it. It was a bring home from the war in the Pacific. My uncle was in the Seabees. I also have a bronze knife with rope handle he brought back, along with an opium pipe! I have a very nice Swiss Victorinox knife, with a picture of the Alps on it. A souvenir of Swiss trip from my sister. A few other knives as well. I guess I need to get picks of them.
I actually joined the Seabee reserves after my fleet Navy active duty. I was a construction mechanic. A gun fire control technician in the fleet Navy.
The point of that Japanese shank is razor sharp btw. It will Kill!

The two Case knives were my Grandfather’s. Case Sportsman, and Case small hunter in basket weave sheath, it has a chip out of the stag handle that has been filled with what appears to be wood putty, the point appears to have been broken and reshaped. It must have lived a hard life.
The deer foot knife was my great uncle’s, it says Joseph Allen & and Son Sheffield, England, it is razor sharp.
