Entry No. 29 — the Boston file — filed under: blacksmithing

Prospect Hill Forge

A one-man teaching smithy on the south side of Guinan Street with no storefront to speak of — just coal and gas forges, an 8:1 (4:1 in advanced classes) student-to-teacher ratio, and a blacksmith named Carl who's been quietly running it for years. Regulars find it through Reddit threads, not ads.

The move: Book "A Taste of Blacksmithing" or the Forged Iron Bottle Opener class together — you'll each hammer out a real object at the anvil and take it home.
