Very impressive knife work, and no mistake.
It’s just that, well, all of those slices look a little thicker than “a human hair”. Not to mention that he was cutting up vegetables, instead of the highly-varied structures inside a body. The project really did require uniform thickness and angles, so I expect that there wasn’t any room for ‘artistic expression’.
But most importantly, I seriously doubt that the project had the budget to hire him, let alone the dozens of similarly-trained folk necessary to complete the project within a reasonable timeframe…
They did not cut the entire body with the hand saw. They freeze the body, cut it into blocks, surround the blocks in plastic, then they grind away the body a little at a time, taking pictures after each shave. She becomes dust afterwards.
