Just on a little safety note, from 8:21 on the video, when you start carving the spoon with your knife, it is an idea to have the work and the blade well away from your inner thigh and femoral artery; leaning forward, with your elbows on your knees is a safer option.
Another little useful thing when hollowing out the bowl of the spoon is to measure it: your upper lip should be able to touch the bottom of the spoon's bowl from handle to tip - an important factor when using it to eat! It also helps you judge how much you need to remove from the back of the bowl, and so its thickness, more accurately. After all, you want to eat with a spoon rather than a log.
Great video and I do like the shape of the resulting spoon. Many thanks for posting it.
