What would an arborist keep in a pouch?

I have made this pouch/wallet as a Christmas gift for by brother in law (shhh!!).

I am very pleased with it as I had no pattern, and so had to plan and design it all from scratch. It is made from knitted hand dyed linen in a nice muted acid green. It is lined with plain linen cloth and the pocket is made from a nice oak-leaf patterned fabric. The colours and pattern seemed appropriate given his profession.

I am very smug to be able to announce that this completes my Christmas present list, and so now I can lean back and relax until the big day. Oh, except for the piece of consultancy work that I just won this morning. (Hoorah!).
