Abstract: A utensil for a digit of a hand includes a cutting board for disposition between a thumb and an index finger. The cutting board is attached to a retainer that receives and retains the thumb such that a cutting surface of the cutting board is oriented toward the index finger. The cutting surface protects the thumb during cutting of items against the cutting surface. Optionally, one or more tools are defined by, or attached to, the cutting board. In a particular example, a utensil for a digit of a hand having a cutting board is useful at least for cleaning, zesting, peeling, and paring or chopping a fruit or vegetable.
