These are Amazon listings of things that I take with me to Italy. Amazon drops products from time to time, let me know if you find any of these to be no longer available. You can probably find similar items at the retailers of your choice.
Chef's Knife with Case - This is a reasonable quality, but very economical Chef's knife with a protective case to keep it from slicing up your luggage.
Foldable Box Grater - This one seems to only come in green, not my favorite color, but this is not a fashion buy.
Flexible Cutting Boards - I have no particular knowledge of this brand. There are plenty of alternatives. Something like this can be a lifesaver when an apartment has no cutting board (or a lousy one)
Universal Adapater - converts multiple electrical formats to all others. Includes USB charging ports.
Simple Adapters - This is all you really need. And they are dirt cheap and light, so stock up.
