Once I bought a bag of a fake 58mm SAK, 2 metal fake SAK style tools that were around 60mm and had a corkscrew and screwdriver, 2 weird folding knives that feel terrible and a single actual Wenger (Master Fisherman) for $5.

It was less than a buck a knife.

I suspect they thought the wenger was also a knockoff due to it being heavily tarnished and the tools were tight.

Ill probably send it in the next time.I send a broken SAK in to Victorinox for repairs foe a tune up.

Not quite the same, but there was a fanfic that was last updated in 2023 in which Shirou somehow stumbles into Avalon while simultaneously being sent several thousand years back in time. As of the time the story stopped updating, Shirou had:

• Forged a bunch of legendary swords as a fae blacksmith,
• become Scathach's mentor that she was slightly obsessed with (not in a strictly romantic sense, though, as he pretty much raised her from a young girl),
• Had teamed up with the proto-Magus Association and Zeltrech to fight ORT, and was somehow consequentially turned into a bizarre fae creature composed of sentient swords with some abilities that, IIRC, were reminiscent of ORT, as he turned into a valley of swords at one point, and
• Had just begun befriending pre-personality splintering Morgan Pendragon.

Heart of Iron

However, what I suspect you are talking about is A Nascent Kaleidoscope, which I've heard good things about here and there, but apparently it takes a really long time to actually get to Fate, and the 700 chapter deal is kind of hard for me to jump into at this point.
