Visit any renaissance fair across the United States this fall and you’ll undoubtedly find a blacksmith. He’ll be sweating away in a tent, pounding on a piece of glowing steel set against an anvil. While the practice of the single blacksmith endures today, high-production ‘works of days past required increasing amounts of muscle. The more tireless the muscle, the better. The manual efforts of the blacksmith were replaced by huge hammers, and the blacksmith needed only to turn the piece between impressions and maintain a healthy respect for the awesome crushing power of the machine.
Last week, blacksmith enthusiasts completed restoration work on the Häfla hammer in Finspang, Sweden. The 333 year old hydraulic hammer hadn’t been used since 1924, when operations ceased at the Häfla Hammerforge. The ‘works was built in 1682 and used the German method of forging, which had been introduced to Sweden in the 1500s. Steel production was revolutionized in the 1800s by the Bessemer process, which resulted in a much stronger product. Continue reading “Retrotechtacular: Häfla Hammerforge Healed”
When your mind’s eye thinks of an ax factory you may envision workers loading blanks into a machine that refines the shape and profile before heading to an annealing furnace. But this is Retrotechtacular, and we’re tickled to feature a look at a different time in manufacturing history. This ax factory tour looks at every step in the manufacturing process at a factory in Oakland, Maine. It was shot on film in 1965 just a few months before the factory shut down. [Peter Vogt] did a great job of shooting and editing the reel, and an equally fine job of converting it to digital so that we can enjoy it on his YouTube channel.
Above you can see the automatic hammer — known as a trip hammer — that is driven by cam action. At this point a lot of work has already been done. Blanks were cut from steel bars by two workers. These were shaped on the trip hammer before being bent in half to create the loop for the ax handle. From there a piece of high-carbon steel was added to form the cutting surface. This brings us to the step above, shaping the two glowing-hot pieces into one.
We don’t want to undermine the level of craftsmanship, and the labor-intensive process shown off here. But we can’t end this write-up without at least mentioning the kitsch that is smoking cigarettes and pipes on the job. At one point a worker actually lights his pipe using a the glowing-hot ax head.
To give you an idea of how this contrasts with modern manufacturing, here’s a How It’s Made episode on axes (although we think whats being made would more appropriately be called hatchets).

[Tony Swatton], blacksmith, armorer, and prop maker, has built hundreds of custom swords for hundreds of movies and TV shows. He’s also the maker behind Man at Arms, the YouTube series where weapons from your favorite shows and movies are recreated, be they improbable weapons from a James Bond movie or a sword from a cartoon. This time, he recreated the Sword of Omens from Thundercats. It’s a work of art in its own right, and amazingly practical for a cartoon sword.
The Sword of Omens is one of [Tony]’s more complex sword making endeavors he’s done. The grip is made of seven different pieces cast in bronze, while the hilt of the sword is over a dozen of different pieces of steel welded together. The jewel in the sword was cut from a piece of glass, carefully ground on a lapidary wheel to a perfect dome.
Of course, this isn’t the only weapon from popular media that [Tony] has crafted. He’s also done Oddjob’s hat from James Bond and Finn’s golden sword of battle from Adventure Time.
