This is my toolbox. There are many like it, but this one is mine. My toolbox is my best friend. It is my life. I must master it as I must master my life. My toolbox, without me, is useless. Without my toolbox, I am useless.
These Swetish peoples, copy the infantry creed: replace toolbox with rifle. On the other hand it might really be a Tool Box, i.e. a box for his tool possibly named Dagmar. As in "Ohhhh, Dagmar!!!"
