I also have one of these knifes that I carried in Vietnam with a brass "spark lite" and some other items in the handle.  I decided to pass it on to my son when he gets older.  He can compare it to my Gerber "wasp blade" survival knife and K-bar, and he can see what we used then.  All the knives saw use but the K-bar the most.  A link to his family past.
