Consider how marketing creates needs where few exist. They sell us cold storage by making room temp feel risky, even for stable goods. You just found the old way often works fine.

Totally get where you're coming from. Rules are there for a reason, and I've seen jobs ruined from a dull blade. Patterned glass is tricky enough without adding worn tools into the mix. Maybe some folks get by with old blades, but it's a risk I wouldn't take... just saying.

Pollen tracing putting a suspect miles from his alibi is crazy accurate. Plants don't forget where they've been, so that evidence sticks. It's scary to think how many cases could be solved with this.

I used to trust those markers without question, figuring they were checked by experts. Hearing about your find with the census records really opened my eyes.

That basic idea is also behind traditional thermos bottles. For another common gadget, consider a simple lever can opener. It uses a pivot point to multiply force, making the cutting easier. Pendulum clocks work on a similar principle, relying on a regular swing to measure time.
