       | Looks a lot like my glass grinder. Nice idea but only cuts
       | cardboard and $249 is crazy expensive.

         | a very limited range of motion, so that it works like a cast
         | saw / oscillatory multi-tool, where the teeth movement is so
         | small that it is within the elastic range of your skin.

         | Yes--startling, but not catastrophic. I first used something
         | like that at age 6. It probably COULD cut flesh if you really
         | tried, but it would take some determination, and just the
         | specter of damage was enough to keep me on good behavior.
         | 
         | I remember it as helping me develop a healthy respect for
         | tools, and also to relate to the material world as something I
         | can manipulate rather than something to be passively consumed.
         | And to manage risks, and confront my fears.

       | This is very cool. The price point puts it beyond the toy
       | category though. Maybe that will come down. Great idea.

       | This could be "bad, actually" if it gives an incorrect impression

       | risky but usually safe when used correctly.

         | You're right, but one presumably would still teach kids to
         | treat this tool with respect. And given that, it seems safer to
         | me as this won't hurt them when they get careless (as kids are
         | wont to do). That way you get a chance to reinforce the safety
         | lesson _before_ they graduate to the dangerous stuff.

       | It's basically a tabletop router for cardboard. That's super
       | cool. The free motion in two dimensions is better than what kids
       | usually get with toy saws and drills.
       | 
       | Routers are great tools but very powerful and finicky. This turns
       | a router into a finger-safe jigsaw, which is a great idea.

       | If anyone in here buys it anyway, they could test if it works
       | with leather, too. That would open up a lot of additional
       | projects.

         | I suspect you could probably work with pretty heavy leather,
         | since the 3mm cardboard it's designed for is going to be pretty
         | comparable to 5-6oz.The bed size might be too small for typical
         | panel sizes though.

       | Would make a nice pairing with:

       | A prototype of this was on Reddit/Imgur a while back:

       | I help run a Makerspace, will definitely be looking into this.
       | Great idea. I know many adults that should start out on such a
       | tool!

       | If it's for cutting cardboard, why not just use a pair of
       | scissors?

         | Have you tried using scissors to cut corrugated cardboard?
         | Especially trying to cut curves? The difficulty seems self-
         | evident.
         | 
         | For straight lines you need something like a box cutter -- with
         | scissors it will neither be easy nor particularly straight.
         | While for even medium-sized curves or smaller details you
         | really do need something like this.

       | I wanted this but the price seems way high.
       | 
       | By the way, could this concept be scaled up to cut wood?

       | Is anyone else bothered by hyperspecific products like this? 95%
       | of what it does can also be done by scissors for 5% of the price
       | and 10x the lifespan.
