An uncle gave my Dad this KA-BAR in 1945.  Dad carried it every day until about 2000, and gave it to me in 2003 or 2004.  I would like to learn anything about it.  (I don't want to sell or trade it as it was my Dad's, and some day I will pass it on.)

(The grids in the photos are 1/4 inch.)

Many thanks.…
