MSR MugMate

Bought this for my grandmother-in-law after she saw me using mine. Great for brewing single cups of coffee or tea. Easy to clean. Mine's in excellent condition after 6 months of regular use.

Gimlet Set

I'm giving gimlet sets to a few lucky in-laws this year. I've found them to be a great time saver whenever I need a hole drilled and precise placement is critical. A few twists and a lovely pilot hole is exactly where you need it.

Hohner Little Lady

The Hohner Little Lady is made in Europe from brass and pear wood. It will play a full scale. Learn 13 songs here.

All the adults in my family agreed this year that they don't want any more stuff in their lives at this point. So instead of buying them gifts, my Cool Tool for the holidays is Oxfam's Unwrapped project: I buy a gift in someone's name, they get a card, I get a tax deduction, and someone in a developing country gets a goat, some chickens, a school desk and chair, some text books, or something else they really need. While I imagine a portion of my donation goes to fund overhead at Oxfam, they are one of the more efficient charities around. Based on what I've read, and heard from acquaintances who work there, most of the money I give them is being put to direct use.

My daughter loves pickles and has expressed some interest in making her own, so I'm thinking of getting her the Leener's Pickling Kit, which can be used to make either dill pickles or sauerkraut, and includes a 2-gallon lead-free ceramic crock made in the U.S.

For Christmas this year I gave my parents a personalized puzzle featuring a custom map of the area around their lake cabin. "From any starting point, we'll create a 400-piece puzzle of a six-by-four-mile area using U.S. Geological Survey maps. A house-shaped piece in the center represents the address you choose. Shows main roads, contour lines, water features, vegetation, and notable buildings. Arrives in a presentation box with space for a personal message." If you search for a promo code, you can save 20%. (Order by 12/14/2009 for Christmas delivery.)
