Fellows,

Just arrived back from Europe. Visited Holland and Holland the people were quite nice even though I wasn't buying. However, the main reason for my post is a tool that I received with my CZ 550 (458 Lott). The tool is shaped like some sort of key. The end has a screwdriver head (flat head) but what puzzles me is in the center of the key. There is a beveled hole that goes straight through the key and is elongated. Does anyone know what this part of the tool is used for?

With Kind Regards
