A client from Alaska brought me a huge halibut fillet (from a fish she'd caught it herself . . . 60 pounds!), about 6 oz. of commercially smoked salmon in a lovely "keepsake" box, about a half pound of silver salmon she'd caught and smoked herself AND my first ULU knife.
I say "first" because I'm already plotting to order another one, a little larger than the one I received as a gift.

As my grandma used to say, this thing cuts through everything like it's hot butter! I've used it on fish, chicken and vegetables. I'm really looking forward to using it more and more.
Mine has a birch handle, but they come in a variety of materials, including rather "exotic" offerings from some manufacturers such as Jade, Caribou Antler, Moose Antler, Fossilized Mammoth, Fossilized Stellar Sea Cow, Fossilized Walrus, Fossilized Oosik, Fossilized Coral Agate, Petrified Wood.
ULUs are available all over the internet, including eBay. They are often available with a butcher block featuring a carved out bowl area that matches the diameter of the ULU blade. That's what I'm getting next.

Have you tried an ULU before?
