This is a full-process documentary showing how a piece of construction rebar (deformed reinforcing bar) is transformed into a working demolition pry bar through traditional Japanese-style hand forging. Rebar is an interesting starting stock because its ribbed surface and medium carbon content make it a common but tricky material — the ribs have to be forged smooth, and the carbon content is inconsistent enough that heat treatment requires judgment rather than a recipe.

What makes this worth watching is the complete workflow: heating cycles in a coal or coke forge, drawing out the shaft, shaping the flattened claw end, splitting and forming the pry tip, and finishing with heat treatment. You get to see how a smith reads color temperature (roughly 800–1000°C for forging), how repeated blows redistribute mass rather than remove it, and how the geometry of a pry bar's business end evolves under the hammer.

Compared to the countless "satisfying blacksmith" shorts that flash through five seconds of grinding, this style of long-form process video actually lets you internalize the sequence of operations — which is the real skill in smithing. If you've ever wondered why forged tools are stronger than machined ones (grain flow that follows the shape of the tool), this is the kind of video that shows it happening.
