Wooden camping utensils?
Wittling a spoon or butter knife is not that difficult, but a 5 prong fork might be a challenge.  A two or three prong design would probably be easier.

As for "duplicating" the particular style and design of the Ozark Trail products, that would depend on the skill of the wittler.  The products that I have seen are plastic and factory smooth.  Personally, if I went to the trouble of hand crafting a set of cutlery, I would want it to look a little rough as that adds a little character to the result.
