I am going to drop this here at the risk of down voting: Japanese nail clippers are world class (much like their scissors).

I've had the same pair, somehow, for 11 years. And to this day using them is delightful. Weird thing to say about clipping nails, but given the frequency of that activity, it's worth noting.

So next time you're in Japan doing all of the culture, and sight seeing, and eating, spend 5m to go to a pharmacy and treat yourself.
