The actual pre-World War 2 Escape Knife photographed in Mike Silvey's book Pocket Knives of the United States Military.  This documented Escape Knife would make an important addition to any advanced collection.

Photos 1 and 2 above were taken of this knife lying over the page from the Silvey's book page 77.  Note the close-up detail of the blades and compare them to the photo.  This is the actual knife.  

The knife's master blade measures 2 9/16".  This knife measures 5 3/16" overall when closed. 

This knife is in excellent condition.  The knife is in the exact condition as it was pictured in Mike Silvey's WW2 book.  All blades have strong snap, and no looseness or wiggle.
