What is the name for a "mechanical wire" I saw in a video? One end of the wire can be plugged into different gears for different gearing ratios. Like a flexible drill extension. More info below

I was watching a video that featured a Negimaru 120 and it has a really interesting drive(?). It’s a vegetable slicer

Here’s a video, a review maybe? It’s in Japanese but that’s not necessarily important… here’s two timestamped links. The first one shows being able to plug into different gears to adjust the thickness of the cut. The second one has a great closeup of it working

Using auto translate, it came up with “joint wire” that led me nowhere. I know it’s basically like a flexible drill extension, but what is that action actually technically called?

That is called a flex shaft. You’ll see them commonly on rotary tool like Dremel. That’s an interesting application in the video. Changing the input on the shaft is basically like shifting a transmission.

  Thank you! Yeah the only term I could think of was worm drive but after looking that clearly wasn’t it
  
  The initial video I saw them moving the “wire” and figured it was electric but then I noticed it was moving as the handle turned so I looked up a video about the device specifically
  
  I understood what it does but yeah the application of it was really cool. Made me think of it as mechanical circuitry

Torque cable might get you some hits, too.

  Oh, I think this is the closest? Definitely looks very similar
  
  Thank you!!

Doubt it’s the right term, but I’d just call it a flexible drive shaft? Doesn’t look more complicated than the ones for drills, it just has gear splines on the ends instead of something else.

It’s just a specialized version of wire rope. Similar to what they use in flexible ratchet extensions.

  That’s super close! I’m curious what the mechanism is called. Like, it’s not a worm drive, it’s a _____?
