I just started using Kramer's Wood Food Oyl on my wooden utensils and I like it very much. By the way, his other products are really exceptional., as I've posted elsewhere ( I have no connecion to the company; I just luse and appreciate their products)

Here's what Kramer writes :
Kramer's Best Wood Food Oyl, is for use on food service items, such as butcher blocks,salad bowls, cutting boards, etc. — anything that will be in direct contact with food. Keeping these utensils clean and safe requires regular washing with lots of hot soapy water and a scalding rinse. These pieces soon dry out, lose their color and will crack and split over time if left untreated. As with other modern wood care products, the formulations offered for the care of wooden food utensils usually have petroleum derivatives, such as mineral oil, as their base. Repeated use may leave a "gummy" build-up. Only materials natural to the wood are capable of furnishing what is necessary for effective care. Food-grade oils, such as the common vegetable oils may be more desirable, but may turn rancid over time. Our Kramer's Best Wood Food Oyl, when applied occasionally as needed, reverses the dryness and at the same time maintains the natural appearance and condition of the piece.
Use your treenware, as it was intended, without worry. If the wood seems dry, work some of the Wood Food Oyl into the wood. Continue to use and care for your pieces in your normal way, reapplying the Wood Food Oyl, as necessary, if you begin to see surface dryness return.
