This is truly the trinket for the person who has everything (or maybe just that lucky someone with a big batch of red walnuts from the farmers' market). But when we saw it, we thought it was an oh-so-lovely stocking stuffer that's practical, too. There's only one problem with the one pictured above.
It's currently out of stock, unfortunately. And the company, Cox & Cox, is in England, so you'd be paying a pretty price for shipping. But their website is worth browsing; there are all kinds of beautiful home goods and some really pretty kitchen items.

Never fear, though. We found another walnut key, made by Alessi, that we think is just as cool (maybe even more so, with it's shiny, heart-shaped edges). And while it's a bit more expensive, it's available in the US.

Obviously a good, old-fashioned nut cracker will do the trick, too. But this keeps the shell in tact and makes it less likely to crush the nut inside. What do you think?
