I've been trying to track down a Japanese woodworking video I saw a while back, where they used a machine that looked like a giant disc sander, but instead of sandpaper, it had blades for trimming the corners and edges of boards. It reminded me of a lathe faceplate chuck with sharp blades that sliced rather than sanded, producing a really smooth finish. It looked quite dangerous, and I have a feeling it might even be out of production for safety reasons. If anyone knows what this machine is or has any leads, I'd really appreciate it—I've been puzzled for weeks trying to remember!

Could it be similar to a uniplane? Those machines are designed to plane surfaces and could potentially match your description. Check out this video for an example: https://youtu.be/qG9pMlfv1-Y?si=nCOh4Nnsmdrzccoo
That sounds like it could be a Marunaka "super surfacer"! It has a design that fits your description with blades instead of sandpaper. You might want to check it out to see if it matches what you remember!
That’s not quite it. The one I remember was more like a heavy-duty disc sander with the whole face rotating, and the blades were fixed on the disc.
Someone reached out to me suggesting it was a Takekawa D-800. Look that up—I've heard it can be pretty dangerous, definitely a 'finger remover'!
I found a video of it [here](https://www.youtube.com/watch?v=R-E9LqxJ5IY). The machine looks super slick!
