Answer:
He used various chisels to shape the figure.
Explanation:
I'm not 100% sure this is true but I remember reading about his works and how most sculptors created their works. I do know sculptors (especially back then) used chisels to shape the figure's body and other areas. So I do believe the first one is the answer you are looking for.
Sorry if anything is wrong, but let me know how it goes if you didn't already answer :)
I usually soak it in hot/warm water for about 30 minutes and then just use a washcloth or something to try and get it out a little at a time and if that doesn't work I soak it in hot soapy water and try it that way. I think the soapy water would do better for you. It usually works for me.
I hope this helps in some way.
