Caveat: today's crop is thin — nearly every candidate is a hashtag-spammed short with no real explanation. This one gets the nod because it names a specific, uncommon tool rather than just "amazing forging."

A billhook is a traditional European hand tool with a hooked blade, used for coppicing, hedgelaying, and cutting green wood — the curve pulls the branch into the cut rather than letting it slip away like a straight blade would. Different regions evolved wildly different billhook patterns (Yorkshire, Kent, Devon, Suffolk), and each geometry reflects the local wood and vegetation.

What makes forging one interesting is that the smith has to manage the transition from a thick spine to a thin cutting edge along a curving blade, then form the socket or tang for the handle. The curve also complicates heat treatment: you want a hard edge but a springy spine so the tool doesn't shatter when it hits a knot.

Even without narration, watching the raw stock progress into a recognizable billhook shape gives you a feel for how much material has to move and where the hammer has to land. A tiny channel (11 subs) doing an obscure traditional tool is exactly the kind of niche craft worth signal-boosting.
