Woodworking tools:
The dado-cutting tool I’ve been seeing used in a video series is the Mafell NFU Groove Cutter.
It’s basically a portable track saw loaded with a single-piece dado blade.
For those unfamiliar, commonly-available dado blades in the US are positively Rube Goldberg designs, comprised of two sawblades sandwiching separate and sharp and fast-whirling blades.
This Mafell brings the table saw to the timber, and with what looks to be a decidedly better (and seemingly safer) blade design than most of the US table saw dado blades I’ve worked with.
Not a cheap power tool, though.
