Limitations on the Conjurer’s Minor Conjuration ability

There are some clearly defined limitations already on the Wizard School of Conjuration’s Minor Conjuration feature, however…

Does normal “wear and tear” count as damage? (e.g. I’m in a fight without a weapon, and create, say, a dagger or club. Will it hold up through the fight?). How about a bottle of ink? Does dipping my pen into it and writing a quick note “damage” the ink?

Is it one piece? ( e.g., can I use it to make a temporary replacement for a set of Thieves’ Tools (which is ‘an item’ on the equipment list) or is it limited to one contiguous item, such as a skillet, or a coil of rope?)
