I'm out of rivets~ (a tool)
Unless I'm missing the nuance of the word 工具, the artist might be mistaken here —rivets are a building material, not a tool
The 23rd of December is
The Day of the Completion of the Tokyo Tower!
Japan's largest radio tower, built back in 1958 in just a year and a half by a group of elite workers with basically no safety equipment at the time!
There goes—hoopDamn, if I fail to catch this I'll just die, right?!(Due to delays in construction work) The workers played a game of "death catch ball" by throwing tools as hot as 800ºC, at a height of 300m with no lifeline, to workers that were 20m above.
Same as above, what they threw was the rivets, that needed to be hot to be fastened to the tower. Apparently, they would catch them with a bucket before putting them.
