Vintage MYSTERY KNIFE from an estate sale.  Four blade. (knife, saw, spike, screw driver)

Im not sure of the maker.  The logo has a bright diamond. The handle also has two marks that I am not familiar with.

Condition:  Wasnt used much if at all. Signs of being opened and closed only. No cracks or chips on handle. Still has its loop.

They will be protected well and insured.

Let me know if you have questions.

Thanks
