I was in the Navy from 73-77. Ended up a BM2. I was lucky, bought my first Case XX then for $10 in the ships store. I still have my Marlin Spike I used to carry to do work with wire cable and do back splices in 21 thread.
I would think you could find a Marlin Spike at a Army Navy surplus store somewhere, they are handy when you need to undo a tight knot,
