I second the microwave idea. Just use the search function and look for "microwave". Personally, I lay green forks on a piece of paper towel and give them a blast for about 30 seconds. Then let them cool. Blast again for about 30 seconds, let cool. Repeat until you get see no more visible water or vapor.
Personally, I would begin with the fork on the right, as it is the chunkiest. That way you can use a good knife, rasp, sandpaper, etc. to shape it to suit your hand. It is easier to take wood away than to add it. I can be a bit of a klutz when it comes to carving, so I always start with a good margin for error. But perhaps you are more adept than I ... be hard not to be!
