For the sake of steel information, I present this mini Imperial USA Interchangeable Mini Knife Tool Kit and pouch.

From what I’ve been told this is the smaller of the 2 kits made by Imperial USA Knives.  The tang stamp dates this from 1956 – 1988.  The shell handles are the very commonly found cracked ice pattern.  The pouch appears to be vinyl.

Please see pics for more details.
