I'm imagining some researcher after years of investment and experimentation eventually accidentally discovering the solution: "you mean it just shuts _itself_ off?!?!".
- exmadscientist 4y agoIt doesn't shut itself off. It just stops cutting. It's like using concrete as a kitchen cutting board: that knife isn't going to do any damage, regardless of whether or not you stop pushing. If you want to laser through metals, you need a different type of laser. Just as getting through concrete needs a different tool (say, a hammer chisel).
- linkdink 4y agoThe line sounded funnier to me in the less pedantic way.
- bombela 4y agoNot a really good comparison I think. A knife blade and a masonry chisel are roughly the same type of carbon steel tempered to a similar hardness. They will both scratch and damage concrete.
- exmadscientist 4y agoI'll grant that it's an imperfect analogy! But would you like to chop through my sidewalk to get to the water main with a santoku?
