Can still get hurt with a jigsaw, to say surface area does not matter also I would think would be wrong
Used a Ryobi 18V Jigsaw on some of my woodworking projects, think it offers amazing versatility in a small package. Fast enough cuts that are a bit lower stress in my opinion than using a circular saw.
The right blades can cut sheet metal, will warn that at least for me went through blades pretty swiftly while cutting sheet metal. Definitely not a plasma torch.
On a different note GCFI Outlets can save lives, less cords and lower voltage when working with power tools potential for not all value out
For Increasing lightness of Desks Hole Saws can be Powerful also has potential to be a more airy design
I have enjoyed the Hole Dozers, have had some issues with material getting stuck in the Hole Saw that is difficult to get out
Less Material without Reducing Strength too much can be powerful for lift
Reduced weight can be valuable up to a point, air able to move through a material can be valuable up to a point. Materials with holes can be lighter, lighter in windy environments can work in unexpected ways.
On a different note, Volume Investments required for Appreciation does Not Always Amp Ideally. I have computers, I have created application that can generate content in a high level of volume, amount, and magnitude. Requirement to amp all combinations is not an all value proposition.
Volume of Meaningful Matters, generated content set to less meaningful not all value added, people contribute where they can how they can based upon the tools they have.
Precomputed file that a Supercomputer could highlight the best generated from? Personal Computers potential for creating Gems in the Rough that Exascale and Zettascale Supercomputers can refine
Investments in Ronnaflop and Quettaflop Supercomputers already in Motion? Like land on the moon and on mars?

Potential for Magnitude and Volume of content to highlight performance of the support systems that made them possible? Yes
Computer and Logic systems, a lot of Paper Saved, Non Null Investment in More Oxygen both Literally and Figuratively
Also a Non Null Investment in Interoperability
Required to Work Together for a better world far from a given
Negate Oversite Amps Less Than Ideally
