Raw Craft with Anthony Bourdain - Episode Four: Bob Kramer



Well, yeah, who doesn't turn a meteorite into a chef's knife in their spare time?

Bourdain visits with Bob Kramer, a master chef's knife maker who goes through the smelting, forging, and heat treating of some pretty spectacular knives.

At about 5:38 (explanation starts) then at 6:18 (actual visual) is one of the - if correctly described - most stunning things I've ever seen in material science. Kramer explains that there is a 'shadow' that moves through the steel as it - as I understand - undergoes the phase change from FCC to BCC, squeezing the carbon into the harder, BCC form of iron.

I am currently looking for confirmation from a second source, however, that what we see is actually what Kramer says it's showing.
