Cardboard, cable, carpet, drywall, twine, plastic packaging and tape, letters, tags on pet toys, pillows, - a good knife made of a modern super steel can be a revelation. Get a good one and keep it handy, and you'll find situations daily where it genuinely makes life easier. For tech people, something like Leatherman skeletool is the ultimate every day carry because of the multi tool, and you can buy custom blades made from powder steel.
