My garlic press. I think it's an OXO. After buying a few cheapies over the years, which always ended up breaking or bending, I finally plunked down the $$ for an expensive one. This one is bombproof and will last me forever.

I used garlic almost everyday, and would not want to go back to mincing by hand.

It's also useful for mincing fresh ginger.

I also have to say how much I love my Henckels knives. A good quality knife set with decent heft is invaluable in the kitchen. Again, I use them every day and would be quite the frustrated cook without them.
