I'm new to whittling and one of my first projects is a butter knife and I'm wondering if there's risk that butter will go inside the wood and spoil?

I'm gonna apply a few coats of food safe oil (one made for cutting boards) and reapply every once in a while. But will it become completely butter proof? I'm assuming it's better to not leave it inside the butter everytime but still, some of it will stay on the knife unless I clean it with soap after every use - which is really inconvenient so is it necessary?
